69-210 25 mm Dia. Dichroic Shortpass Filter; t=1.05mm 900nm
The 69-210 is a Dichroic Shortpass Filter, boasting a 25 mm diameter and a thickness of 1.05mm. This filter, sourced from the reputable vendor Edmund Optics, is designed to transmit light below a specified wavelength while reflecting light above it. In this case, the cut-off wavelength is 900nm, meaning it allows the passage of wavelengths shorter than 900nm and blocks those longer than 900nm.
The filter's coating is a crucial component, and in this model, both the front and back are coated with EDM 69-186. This coating enhances the filter's performance, ensuring the accurate transmission and reflection of light at the specified wavelength.
The 69-210 is shaped as a Thin Lens, which is a type of lens with a small thickness compared to its diameter. This shape allows for minimal distortion and a wide field of view, making it suitable for a variety of optical applications.
