695FG07-50 50mm Dia. RG-695 Colored Glass Long Pass Filter by Andover Corporation

The 695FG07-50 is a 50mm diameter, thin lens, colored glass long pass filter, manufactured by the Andover Corporation. This filter is part of their extensive catalog of optical elements, which are sourced from various vendors worldwide.

The filter is designed with a long pass characteristic, specifically at a wavelength of 695 nanometers. This means that it allows light of wavelengths longer than 695nm to pass through, while blocking or attenuating shorter wavelengths. The filter's geometry includes a diameter of 50mm and a thickness of 3mm, making it suitable for a wide range of optical applications.

The 695FG07-50 filter features a coating on both the front and back surfaces, identified as 'and 695fg07'. This coating is likely designed to enhance the filter's performance, such as by reducing surface reflections or increasing transmission at the specified wavelength.

The filter's physical data indicates a cut-on wavelength of 695nm and a cut-off wavelength of 0nm. This suggests that the filter begins to transmit light at 695nm, and continues to transmit all longer wavelengths without significant attenuation.
