1. Lens Diameter and Mount Type

• Diameter: Typically ranges from 2mm to 6mm, ensuring minimal visibility when installed.
• Mount Type: Compatible with M12/S-Mount (also known as “board lenses” or “miniature lenses”), which thread directly into PCB cameras. This design eliminates the need for bulky adapters, making it ideal for space-constrained applications.

2. Focal Length and Field of View (FoV)

• Focal Length: Available in fixed focal lengths (e.g., 2.8mm, 3.6mm, 4mm) and vari-focal options for adjustable magnification.
• Field of View: Wide-angle variants offer FoV up to 180°, perfect for capturing expansive areas in a single frame. Fisheye lenses provide even broader perspectives, while low-distortion models ensure image clarity.

3. Aperture and Light Sensitivity

• Aperture: Fixed or manual iris options allow control over light intake, with f-numbers as low as f/1.2 for superior low-light performance.
• Low-Light Sensitivity: Designed to excel in dimly lit environments, these lenses capture crisp images even in challenging conditions.

4. Image Quality and Coating

• Resolution: Supports megapixel sensors (1MP, 2MP, 5MP, and higher), ensuring high-definition output.
• Coating: Multi-coating technology reduces glare and enhances contrast, while IR-corrected lenses are optimized for day/night security cameras.

5. Durability and Environmental Resistance

• Material: Constructed from high-grade glass and metal alloys for longevity.
• IP Rating: Dust- and water-resistant designs (IP67 or higher) make them suitable for outdoor and industrial use.
