LOPF-25C-341 25 mm Dia. Mounted Longpass Filter; t=3.5mm 350-500nm

OptoSigma's LOPF-25C-341 is a 25 mm diameter Longpass Filter, designed for use in optical systems that require the blocking of shorter wavelengths while transmitting longer wavelengths. This filter is specifically designed for use in the 350-500nm range, making it ideal for applications such as fluorescence microscopy, spectroscopy, and other optical systems where specific wavelength selection is crucial.

The filter is constructed with a circular geometry, boasting a 25mm diameter and a thickness of 3.5mm. This robust construction ensures durability and stability within your optical system. The filter is coated on both the front and back with Opt Lopf-341, a specialized coating that enhances the filter's performance and longevity.

The LOPF-25C-341 features a UVFS MAL-1965 material ID, which is known for its excellent optical properties and durability. The physical data of the filter indicates a cut-on wavelength of 341nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths shorter than this.

This filter is currently in stock and available for immediate purchase through the OptoSigma website. With its high-quality construction, specific wavelength selection, and reliable performance, the LOPF-25C-341 is an excellent choice for a wide range of optical applications.
