FSQ-RG850 50.8 x 50.8 mm Colored Glass Absorptive Longpass Filter 850nm

The FSQ-RG850 is a rectangular longpass filter, measuring 50.8 x 50.8 mm, designed for use in optical systems. This filter is sourced from the reputable vendor MKS/Newport and is available for purchase through their website. The catalog number for this product is FSQ-RG850.

This filter is specifically designed for use in the infrared region of the spectrum, with a cut-on wavelength of 850nm. This means that it will begin to transmit light at this wavelength, making it ideal for applications where infrared light needs to be isolated or detected. The cut-off wavelength for this filter is 0nm, indicating that it will block all wavelengths of light below 850nm.

The FSQ-RG850 filter is made from a colored glass absorptive material, which is designed to absorb unwanted wavelengths of light while transmitting the desired wavelengths. This filter has a thickness of 3mm, providing excellent durability and stability in optical systems.

The coating on both the front and back of this filter is New RG850. This coating is designed to enhance the performance of the filter, improving its transmission and blocking characteristics. The shape of the filter is thin lens, which is designed to minimize optical aberrations and distortions.
