46-439 25.4 mm Dia. Hoya U-340 (UV) Black Colored Glass Bandpass Filter 340nm

The 46-439 Hoya U-340 is a 25.4 mm diameter UV bandpass filter with a center wavelength of 340nm. This filter is sourced from Edmund Optics and is part of their extensive catalog of optical elements. The U-340 filter is designed for use in UV applications and features a black colored glass bandpass to enhance its performance.

The filter is made from UVFS Mal-1965 material, which is specifically designed for UV applications. It has a geometry of 25.4mm in diameter and a thickness of 2.5mm, making it suitable for a wide range of optical systems. The physical data of the filter includes a center wavelength of 340nm, which is the wavelength at which the filter is most effective.

The U-340 filter features a coating on both the front and back surfaces. This coating, identified as EDM 46-096, is designed to enhance the performance of the filter and protect it from environmental factors. The filter has a shape of a thin lens, which is a common shape for optical filters due to its compact size and ease of integration into optical systems.
