JSD2226 2.2mm Non-Distortion M7 Lens for OV9732 1/4" Sensors – 5MP, <−0.6% TV Distortion
JSD2226 2.2mm Non-Distortion Lens: IR and Visible-Light Questions Answered
JSD2226 2.2mm non-distortion lens for 1/4" sensors — TV distortion under −0.6%, M7 mount, 5MP, TTL 9.84mm. IR vs. visible-light configuration, sample and 100-pcs MOQ paths explained.
Key takeaway: The JSD2226 addresses distortion at the design stage, holding TV distortion below −0.6% at an ultra-wide 2.2mm focal length. The IR-versus-visible question is a configuration decision, resolved through IR-cut or IR-pass filter choice and CRA matching at order time. Samples, technical data, and 100-pcs MOQ quotations are available for evaluation.
The Two Lens Decisions a 1/4" Module Can't Easily Undo
A compact camera module settles three things early: the image sensor, the PCB layout, and the optical stack. The lens is typically chosen last — and it is where late-stage redesigns surface, because two lens properties shape the entire system without appearing on any single spec line.
Distortion. A 2.2mm focal length reaches a wide field of view by bending light steeply. Inexpensive designs accept several percent of barrel distortion as the trade-off, and that error is pushed downstream into software. Line-fit calibration for barcode decoding, OCR, or any measurement that depends on straight edges becoming an ongoing engineering task instead of a one-time setup.
Spectrum. A lens configured for visible light and one configured for near-infrared are different products. An 850 nm or 940 nm illuminator paired with the wrong filter produces a dim, soft, or ghosted image — a mismatch the sensor cannot correct.
The JSD2226 addresses the first issue at the design stage. The second is a configuration decision, and it is the detail most buyers need confirmed before ordering.
What "Non-Distortion" Actually Means
In optics, the term describes a lens that stays close to rectilinear projection — straight lines in the scene remain straight in the image. Wide-angle designs routinely trade this property away to gain field of view, which is why low-cost 2.2mm lenses can show visible barrel curvature.
The JSD2226 holds TV distortion below −0.6%. At an ultra-wide 2.2mm focal length, that figure leaves little curvature to remove in post-processing, and the practical effects are concrete:
Line-fit and De-Warping routines converge on the first pass rather than requiring iterative tuning.
Barcode and OCR geometry stays proportional across the frame, so corner reads are as dependable as center reads.
Smaller correction maps mean less CPU and memory budget reserved for image processing.
That is the engineering value behind the number.
Inside the JSD2226: Specifications and What They Change
| Specification | Value | Why It Matters |
|---|---|---|
| EFL | 2.20 mm | Wide field of view in a short optical path |
| F/No. | F2.6 | Low-light throughput for small-pixel 1/4" sensors |
| Field of View (D/H/V) | 91° / 82° / 52° | Wide, rectilinear — coverage without curvature |
| TV Distortion | < −0.6% | Minimal correction work downstream |
| Optical Construction | 2G3P (2 glass + 3 plastic) | Glass elements limit focus drift; plastic aspheres control size and cost |
| Mount | M7 | Widely supported holder and module ecosystem |
| Barrel Diameter | φ8 mm | Fits tight mechanical envelopes |
| TTL | 9.84 mm | Keeps total module height low |
| Resolution | 5 MP | Matched to current 1/4" sensor pixel counts |
| Image Circle | 1/4" (Ø5.1 mm) | Defines the sensor compatibility ceiling |
Sensor match: the JSD2226 is the designated optical pairing for the OmniVision OV9732 (1/4"). It also fits other 1/4" sensors within an image circle up to Ø5.1 mm.
Why the 2G3P stack matters: all-plastic stacks are cheaper to build but shift focus as temperature moves. The JSD2226's glass elements hold focus over a wider temperature range while the plastic aspheres keep the assembly compact — the difference between a fixed-focus module that stays in spec and one that needs re-calibration in the field.
IR or Visible Only? The Honest Answer
This is the question the spec sheet leaves open, so it receives a factual rather than promotional answer.
What the documentation states:
The standard specification database carries no explicit IR-design parameter for the JSD2226. No IR capability is claimed that has not been verified in writing.
The 2G3P construction includes glass elements, and glass generally transmits near-infrared more readily than all-plastic designs. This is an indicator, not a guarantee.
What ultimately governs IR behavior is the filter configuration shipped with the lens — an IR-cut filter for visible-only imaging, or an IR-pass / no-IR-cut build for IR-sensitive imaging.
Why the choice is not interchangeable:
IR-cut: blocks near-infrared so daylight color rendering stays accurate. Standard for color imaging.
IR-pass / no IR-cut: passes NIR so the sensor can register 850 nm or 940 nm illumination in low light. Common in night-vision and machine-vision setups.
CRA matching: the lens's Chief Ray Angle must align with the sensor's microlens CRA. A mismatch costs brightness and color fidelity toward the frame edges, and the match is specific to the sensor.
The practical answer: IR-cut and IR-pass filters, along with custom CRA matching, are standard customization services at JSD. The JSD2226 platform can be specified for either direction, so the IR question is resolved at order configuration rather than being a dead end.
"Engineering takeaway: provide the target sensor and the illumination wavelength. JSD's optics team will then specify the matching filter and CRA. For buyers evaluating the standard part first, a written confirmation of the baseline filter configuration is available on request."
— JSD OpticsWhere the JSD2226 Fits
One optical platform, and the same geometric accuracy in a small M7 body, applied to five different problems.
Barcode and document scanning — decoding depends on proportional geometry; low distortion keeps codes and text legible from center to edge, lowering reject rates.
Embedded and IoT cameras — the φ8 mm barrel and 9.84 mm TTL fit enclosures where a standard M12 assembly will not.
Drones and robotics — reduced post-processing load and glass-stabilized focus hold up under vibration and temperature swing.
Smart-home and security modules (1/4" tier) — 5MP resolution and stable focus at a cost position suited to consumer volumes.
Gesture and depth modules — rectilinear geometry keeps triangulation math predictable, simplifying calibration.
Standard 2.2mm Lens vs. JSD2226 2.2mm Non-Distortion Lens: What Changes
| Consideration | Typical Low-Cost 2.2mm Lens | JSD2226 |
|---|---|---|
| Distortion | Several percent barrel; correction required | Minimal correction needed |
| Focus stability | All-plastic; drifts with temperature | 2G3P hybrid with glass elements |
| Integration | Holder fit varies by supplier | M7 thread, φ8 mm barrel, 9.84 mm TTL |
| Downstream cost | More calibration and support effort | Less software and support load |
| IR / CRA flexibility | Usually fixed at purchase | IR-cut, IR-pass, and custom CRA available |
The relevant comparison is not which sheet looks stronger, but how much engineering effort each option removes from the program after the part is chosen.
Engineering Considerations Before Specifying
Field-of-view envelope. At 91° diagonal (82° H / 52° V), the JSD2226 is wide but rectilinear — the right fit where geometry must hold. Projects needing fisheye-style coverage require a different optical solution.
Resolution ceiling. The design is optimized for 5MP / 1/4". Designs moving to higher resolution or larger sensors should be matched to another lens in the family.
Mechanical clearance. The M7 thread, φ8 mm barrel, and 9.84 mm TTL set the holder and housing envelope. Confirming these against the module drawing early avoids a re-spin later.
Environmental sealing. The standard part is not IP-rated; sealing is handled at the housing level. Projects with ingress requirements should plan the sealing strategy alongside lens selection.
Why Source the JSD2226 Through JSD
JSD Optics is an imaging lens developer and manufacturer established in 2009, with roughly 200 employees and an approximately 1,000㎡ production facility, certified to ISO 9001 and IATF 16949. The company supplies standard and customized imaging lenses specifically to camera module manufacturers.
That focus shapes what a JSD order includes:
Sensor-first matching. Lenses are recommended from the image sensor outward, beginning with the OV9732 for 1/4" designs.
Customization as a standard service. IR-cut and IR-pass filters and custom CRA matching are routine engineering work, not exceptions.
Documentation honesty. Where a parameter is not confirmed on the datasheet, it is routed to the optics team rather than estimated.
Sample-to-volume continuity. Evaluation quantities and production volumes come from the same optical specification.
For a module program, the supplier's role is to remove optical risk from the schedule — which is what the sensor-matching and customization capability is built to do.
Next Step: Sample, Data, or Volume Quote
Pick the path that matches the current stage:
Ready to evaluate — request a 10-pcs sample batch and test the JSD2226 in the target module.
Still in specification — request MTF, distortion, and relative-illumination data, plus confirmation of the IR-cut configuration for the intended sensor. Technical data is provided directly by the optics team rather than through a datasheet download.
Planning production — request a 100-pcs MOQ quotation, and a custom IR filter / CRA matching consultation if the application images under NIR.
A precise response is faster with three details: the target sensor (OV9732 or another 1/4" part), the illumination requirement (visible-only or IR-sensitive), and the sample ship-to address with target date.
❓ Frequently Asked Questions
The two questions a spec sheet leaves open — IR behavior and sensor matching — answered directly.
Is the JSD2226 designed for IR light or visible light only?
The standard datasheet specifies no IR parameter. The 2G3P stack's glass elements favor NIR transmission, but IR behavior is set by the filter configuration. Both IR-cut and IR-pass builds, with custom CRA matching, can be specified.
Which sensor is the JSD2226 designed for?
It is the designated match for the OmniVision OV9732 (1/4"), and also fits other 1/4" sensors within an image circle up to Ø5.1 mm.
Can samples be ordered before a production commitment?
Yes. A 10-pcs evaluation batch is available so the optics can be validated in a real module, followed by volume pricing at the 100-pcs MOQ tier.
Does the standard part meet IP67?
No. The standard JSD2226 is not IP67-rated; ingress protection is addressed at the housing level.
What technical data can be provided for evaluation?
MTF, distortion, and relative-illumination data are supplied directly by the optics team, along with written confirmation of the IR-cut configuration for the intended sensor.
