32-766 50.8 x 50.8 mm SCHOTT RG695 Black Longpass Color Glass Filter 695nm

The 32-766 is a 50.8 x 50.8 mm SCHOTT RG695 Black Longpass Color Glass Filter, designed to transmit light with wavelengths longer than 695nm while blocking shorter wavelengths. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.

The filter is made of color glass, a type of optical filter that uses colored glass to block specific wavelengths of light. This particular filter is rectangular in shape, making it suitable for use in a variety of optical systems. The filter has a thickness of 3mm, providing durability and stability.

The 32-766 filter features a cut-on wavelength of 695nm, meaning it begins to transmit light at this wavelength. It has a cut-off wavelength of 0nm, indicating it blocks all wavelengths of light below this point. This makes it an effective longpass filter, allowing for the selective transmission of longer wavelengths.

The filter's coating further enhances its performance. Both the front and back surfaces of the filter are coated with EDM 54-660, a proprietary coating developed by Edmund Optics. This coating helps to improve the filter's durability and optical performance.

The filter's geometry is defined by its width (50.8mm) and height (50.8mm), making it a square filter. Its shape is classified as a thin lens, indicating it has a thin, lens-like profile. This shape is often used in optical systems where a thin, lightweight element is required.
