Your eyes are unique. Your lens should be too.

Let’s face it: standard wide-angle lenses are great for doorbells and dashcams, but when it comes to high-security biometrics, they just don't cut it. If you are designing an iris recognition system, you don't need to see the user’s ears, the wall behind them, or the ceiling. You need to see the eye—and you need to see it perfectly.

Enter the JSD9332. This isn't a consumer-grade toy; it is a specialized optical instrument designed to unlock doors, secure data, and verify identity with pinpoint accuracy.

Here is why the JSD9332 is the perfect "eye-witness" for your biometric hardware:

1. The "Sniper" Focus (21° Narrow Angle)

In the world of iris scanning, pixel density is everything. Most M12 lenses spray pixels everywhere with wide fields of view.
The JSD9332 takes a different approach. With a 9.3mm Effective Focal Length (EFL) and a tight 21° Field of View, this lens acts like a spotlight. It zooms in on the target area (the eye) to maximize resolution where it counts. It ensures that every unique pattern in the iris is captured with sufficient detail for your algorithms to process.

2. Geometry You Can Trust (<0.1% Distortion)

Biometrics is a game of math. If your lens warps the image, it changes the mathematical map of the iris, leading to false rejections. ("Sorry Dave, I can't let you in.")
The JSD9332 boasts <0.1% optical distortion. That is virtually zero. It delivers a flat, true-to-life image that ensures the pattern the sensor sees matches the reality of the user, drastically improving recognition speed and accuracy.

3. Compact Security (TTL 12.42mm)

Security modules need to be sleek and unobtrusive. You can’t have a massive lens protruding from a turnstile or a wall scanner.
With a Total Track Length (TTL) of just 12.42mm, this lens is tiny. It utilizes the industry-standard M12 thread, allowing it to drop seamlessly into compact housings while maintaining a robust 2MP resolution.

4. Precision Matched (1/4.5" Sensor)

This lens isn't a "one-size-fits-all" compromise. It is optically engineered for 1/4.5" image sensors. This specific pairing ensures that you get edge-to-edge sharpness without the wasted light or vignetting common in mismatched setups. Combined with an F/3.2 aperture, it offers the depth of field needed to keep the iris in focus even if the user shifts slightly.

The JSD9332 is not for taking selfies. It is built for Identity Management, Access Control, and Biometric Security.

When security is on the line, don't rely on generic glass. Choose the lens that focuses on what really matters.
