36-308 25.4 mm Dia. SCHOTT BG38 (VIS) Blue-Green Colored Glass Bandpass Filter 470nm
The 36-308 is a 25.4 mm diameter bandpass filter from Edmund Optics, designed for use in the visible spectrum. This filter features a center wavelength of 470nm, making it ideal for applications that require the selective transmission of blue-green light.
The filter is made from SCHOTT BG38 (VIS) glass, a material known for its excellent optical properties and durability. The glass is coated with a thin film on both the front and back surfaces, identified as EDM 46-433. This coating enhances the filter's performance by reducing reflection and increasing transmission.
The geometry of the filter includes a diameter of 25.4mm and a thickness of 3mm. This thin lens shape ensures minimal distortion and maintains the integrity of the transmitted light. The filter's physical data includes a center wavelength of 470nm, which is the wavelength at which the filter has its maximum transmission.
