49-471 35 x 35 mm N-BK7 45 deg Reflective Red Dichroic Filter; t=3 mm 400-750nm

The 49-471 is a 35 x 35 mm dichroic filter, designed with a 45-degree angle of incidence and manufactured by Edmund Optics. This filter is made from N-BK7 Schott glass, a popular choice due to its excellent optical properties and high damage threshold. The N-BK7 Schott glass is 3 mm thick, providing durability and resistance to mechanical stress.

The 49-471 filter is designed to reflect a specific wavelength of 588 nm, making it ideal for applications that require the separation or enhancement of red light. The cut-on wavelength is 615 nm, and there is no specified cut-off wavelength, indicating that this filter allows transmission of wavelengths shorter than 615 nm.

The filter features a dichroic coating on both the front and back surfaces, identified as EDM 47-263. This coating is designed to reflect a specific wavelength while transmitting others, enhancing its performance in red light applications. The coating also provides protection to the glass surface, reducing the risk of damage and contamination.

The 49-471 filter has a rectangular shape, with a width of 35 mm and a height of 35 mm, making it suitable for use in various optical systems. The filter is categorized as a thin lens, indicating a low profile and minimal impact on the overall optical path.
