45-066 25.4 mm Dia. SCHOTT N-WG305 Longpass Color Glass Filter 309nm

The 45-066 is a 25.4 mm diameter Longpass Color Glass Filter, specifically designed by SCHOTT under the product code N-WG305. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website. The filter's primary function is to allow light transmission above a certain wavelength while blocking lighter wavelengths, making it ideal for applications that require the isolation of specific light spectra.

The filter's cut-on wavelength is 309nm, meaning it begins to transmit light at this point of the spectrum. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths below the cut-on point. This specific model is designed for use in ultraviolet (UV) applications, making it suitable for a wide range of scientific and industrial uses.

The filter is constructed with a Thin Lens shape, featuring a thickness of 3mm. This design ensures minimal distortion of the light path, making it ideal for precision applications. The filter's diameter is 25.4mm, a standard size that allows for easy integration into existing optical systems.

The 45-066 filter is coated with EDM 54-646 on both the front and back surfaces. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency. The coating also provides chemical resistance, ensuring the filter's durability and longevity.
