66-076 50 mm Dia. Hoya L-38 Longpass Color Glass Filter 380nm

The 66-076 50 mm Dia. Hoya L-38 Longpass Color Glass Filter is a high-quality optical component designed for applications that require longpass filtering at a wavelength of 380nm. 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 a Color Glass type, which is known for its ability to selectively transmit light within a specific wavelength range while blocking other wavelengths. This particular model is designed with a 50mm diameter and a thickness of 2.5mm, making it suitable for a wide range of optical systems.

The physical data of the filter indicates that it has a cut-on wavelength of 380nm, meaning it begins to transmit light at this wavelength. The cut-off wavelength is 0nm, indicating that it continues to transmit all wavelengths beyond 380nm. This makes it ideal for applications that require the transmission of ultraviolet light and beyond.

The filter features a Thin Lens shape, which is designed to minimize optical aberrations and distortions. This is particularly important in applications that require high precision and accuracy, such as scientific research, medical imaging, and industrial inspection.

The front and back surfaces of the filter are coated with the EDM 66-076 coating, which is specifically designed to enhance the performance of the filter. This coating helps to reduce reflections, increase transmission, and protect the filter from environmental damage.
