69-201 25 mm Dia. Dichroic Shortpass Filter; t=1.05mm 450nm

The 69-201 is a Dichroic Shortpass Filter, sourced from the reputable optical components vendor, Edmund Optics. This filter, with a diameter of 25 mm, is designed to selectively pass wavelengths shorter than 450 nm while blocking longer wavelengths, making it ideal for various applications requiring short-wavelength filtration.

The filter boasts a thickness of 1.05 mm, providing sufficient structural integrity for most applications. It is crafted from UVFS Mal-1965, a material known for its optical properties, further enhancing the filter's performance. The filter's geometry, including its diameter and thickness, is shaped in a Thin Lens configuration, optimizing its optical characteristics.

The 69-201 features a dichroic coating on both the front and back surfaces, specifically EDM 69-177. This coating ensures the filter's selective wavelength transmission, contributing to its high-performance characteristics. The filter's cut-on wavelength is 0 nm, and its cut-off wavelength is 450 nm, providing a sharp cut-off for short-wavelength filtration.
