11-481 25 x 25 mm Red Dichroic Filter; t=2mm 605nm

The 11-481 is a 25 x 25 mm Red Dichroic Filter with a thickness of 2mm, sourced from the renowned optical components vendor, Edmund Optics. This filter is designed to selectively transmit or reflect light based on its wavelength, making it an essential component in various optical systems.

The filter's primary wavelength is 588nm, and it features a dichroic coating on both the front and back surfaces, specifically the EDM 52-527 coating. This coating is designed to reflect or transmit light at specific wavelengths while allowing other wavelengths to pass through. In this case, the filter is designed to handle red light, making it ideal for applications involving red lasers or other red light sources.

The filter is cut on at 605nm, meaning it starts to transmit light at this wavelength. Below this wavelength, the filter will block or reflect light. The cut-off wavelength is 0, indicating that it will transmit all wavelengths above 605nm.

The filter is made from borofloat33, a type of glass known for its excellent optical properties and durability. This material ensures the filter maintains its performance over time and under various environmental conditions.

The filter's geometry is rectangular, with a width of 25mm and a height of 25mm, making it compatible with many optical systems. The thickness of 2mm provides structural rigidity while minimizing optical distortions.

According to the vendor's website, the filter is currently in stock, ensuring quick delivery times for your optical projects. For more information, you can visit the product page at https://www.edmundoptics.com/p/25mm-square-red-dichroic-filter/40590/.
