• Infrared lenses covering response bands from 700nm to 2000nm with focal lengths from 12mm to 35mm.
• Applications include specialized imaging requiring infrared sensitivity.

6. 3D Oblique Lenses

• Models such as DZO_SM2535A, DZO_SM3530A with tilt angles ±15° and magnification ranges around 0.49x to 1.15x.
• Designed for 3D imaging applications with 1" sensor compatibility.

7. Lens Customization Process

1. Customer requirements gathering and preliminary design.
2. Cost and development cycle evaluation.
3. Customer confirmation of costs and delivery schedule.
4. Project initiation, design output, and engineering sample production.
5. Sample testing followed by mass production.
