69-181 12.5 mm Dia. Dichroic Shortpass Filter; t=1.05mm 650nm
The 69-181 is a Dichroic Filter with a 12.5 mm diameter and a thickness of 1.05mm, specifically designed for use at a wavelength of 588nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.
The filter is made from UVFS Mal-1965 material, a common choice for optical applications due to its excellent properties. The Dichroic Filter is designed to reflect or transmit light depending on the wavelength, making it an essential component in various optical systems.
The 69-181 has a cut-on wavelength of 0nm and a cut-off wavelength of 650nm. This means it allows light below 650nm to pass through while blocking light above this wavelength. The filter's coating, applied to both the front and back surfaces, is designated as 'edm 69-181'. This coating enhances the filter's performance and durability.
The filter's geometry, including its diameter and thickness, is designed to fit into various optical systems. The 12.5 mm diameter is a common size for many optical components, making it easy to integrate into existing setups. The 1.05mm thickness is also optimized for performance and compatibility.
