20CGA-385 2 x 2 in Square Colored Glass Alternative Longpass Filter 385nm
The 20CGA-385 is a Longpass Filter from MKS/Newport, designed with a 2 x 2 in square shape and a thickness of 1.1 mm. This filter is specifically engineered for use in optical systems that require longpass filtering at a wavelength of 385nm.
The filter is made from UVFS Mal-1965, a material known for its optical properties and durability. It features a cut-on wavelength of 385nm, meaning it begins to transmit light at this wavelength and continues to do so as the wavelength increases. The cut-off wavelength is 0nm, indicating that it transmits all wavelengths beyond its cut-on point.
The 20CGA-385 filter has coatings on both the front and back surfaces, designated as 'new 20cga-385'. This coating enhances the filter's performance and durability, ensuring it maintains its optical properties over time.
The filter's geometry includes a width of 50.8 mm and a height of 50.8 mm, making it suitable for use in a variety of optical systems. It is designed in the shape of a thin lens, which can be beneficial in systems where space is limited or precise focusing is required.
According to the vendor's information, the 20CGA-385 is currently in stock and available for purchase. For more detailed information, including pricing and availability, please refer to the vendor's website using the provided weblink.
