66-038 12.5 mm Dia. Hoya L-37 Longpass Color Glass Filter 370nm
The 66-038 is a 12.5 mm diameter color glass filter manufactured by Hoya, available through Edmund Optics. This filter is specifically designed for longpass applications, with a cut-on wavelength of 370nm.
The filter is made from UVFS Mal-1965 material, a detail that is crucial for understanding its optical properties and potential applications. The geometry of the filter includes a diameter of 12.5mm and a thickness of 2.5mm, making it a compact yet robust option for various optical setups.
The coating on both the front and back of the filter is EDM 66-038, which plays a significant role in its performance. This coating enhances the filter's ability to block or transmit specific wavelengths, contributing to its longpass functionality.
The filter's physical data indicates that it is cut on at 370nm and cut off at 0nm. This means that it begins to transmit light at 370nm and continues to do so for shorter wavelengths. The 'Thin Lens' shape of the filter suggests that it is designed to minimize optical aberrations, ensuring clear and accurate optical transmission.
