When it comes to precision imaging in low-light or infrared (IR) environments, M12 lenses with 850nm IR pass filter stand out as a game-changing solution. Designed to optimize performance in surveillance, machine vision, and night-vision applications, these lenses combine compact design with cutting-edge optical technology.

Why M12 Lenses with 850nm IR Pass Filter Matter

The integration of an 850nm IR pass filter in M12 lenses ensures that only infrared light within the 850nm wavelength range passes through, blocking visible light and other IR wavelengths. This makes them ideal for applications requiring discreet surveillance, as 850nm IR is invisible to the naked eye but detectable by most CMOS/CCD sensors. Towin’s M12 lenses are engineered to minimize chromatic aberration, enhance contrast, and maintain sharp focus even in challenging lighting conditions.

FAQs

1. What is the primary benefit of an 850nm IR pass filter?

The 850nm IR pass filter blocks visible light and unwanted IR wavelengths, allowing only 850nm infrared light to pass. This enhances image clarity in low-light conditions and ensures compatibility with IR-sensitive sensors.

2. Are M12 lenses compatible with all board cameras?

Yes, M12 lenses use a standard S-mount thread, making them compatible with most CMOS/CCD board cameras. However, always verify the sensor size and back focal length requirements.

3. Can M12 lenses be used outdoors?

Absolutely. Towin’s lenses are designed to withstand temperatures from -20°C to +60°C and are resistant to dust and moisture, making them ideal for outdoor applications.

4. How do I choose the right focal length for my application?

The focal length determines the field of view. Shorter focal lengths (e.g., 2.8mm) offer a wider angle, while longer focal lengths (e.g., 8mm) provide zoomed-in detail. Towin’s experts can help you select the optimal lens based on your needs.

5. Do Towin’s M12 lenses support high-resolution cameras?

Yes, Towin offers M12 lenses that support resolutions up to 5MP, ensuring compatibility with modern high-definition imaging systems.
