35-890 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 290nm

The 35-890 is a Bandpass Filter with a 50 mm diameter and a thickness of 3.5 mm, designed for use in applications requiring a 10nm bandwidth at the 290nm wavelength. This filter, offered by Edmund Optics, is a crucial component for applications demanding precise wavelength selection and rejection of unwanted spectral ranges.

The filter's primary function is to transmit light within the specified range (285nm to 295nm) while blocking other wavelengths. This characteristic is particularly useful in applications such as fluorescence microscopy, spectroscopy, and other scientific research where specific wavelength control is essential.

The 35-890 features hard coating on both the front and back surfaces, enhancing its durability and resistance to scratches and environmental factors. This coating also helps maintain high transmission and low reflectance, ensuring optimal performance.

The filter's geometry, with a 50mm diameter and 3.5mm thickness, allows for easy integration into various optical systems. Additionally, the UVFS MAL-1965 material ID ensures consistent performance and compatibility with other optical components.
