34-302 25 mm Dia. High Performance Longpass Filter with 375 nm Cut-On

The 34-302 is a high-performance longpass filter, measuring 25 mm in diameter and 1.5 mm in thickness, sourced from Edmund Optics. This filter is specifically designed for use in optical systems where a longpass filter is required, and it boasts a cut-on wavelength of 375 nm.

The filter is made from UVFS Mal-1965 material, a high-performance optical material known for its excellent transmission characteristics and durability. The filter's longpass functionality is achieved through a specialized coating on both the front and back surfaces, denoted as EDM 34-301. This coating ensures high transmission for wavelengths above the cut-on while effectively blocking shorter wavelengths.

The 34-302 filter is designed in a thin lens shape, which is beneficial for applications where space is a constraint. It is currently in stock and available for immediate purchase through the Edmund Optics website. The filter's specifications make it an ideal choice for a wide range of applications, including but not limited to, fluorescence microscopy, spectroscopy, and other optical systems where longpass filtration is necessary.
