FLH355-10 Premium Bandpass Filter; Dia:25 mm; CWL=355nm; FWHM=10nm

The FLH355-10 Premium Bandpass Filter is a high-quality optical component designed for precise wavelength selection, manufactured by Thorlabs. This filter is circular in shape with a diameter of 25 mm and a thickness of 2 mm, making it compatible with a wide range of optical systems.

The filter is specifically designed for use at a central wavelength (CWL) of 355 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows light within a narrow band around 355 nm to pass through while blocking out other wavelengths. This feature makes it ideal for applications that require high spectral purity and wavelength selectivity, such as laser systems, spectroscopy, and bio-imaging.

The FLH355-10 filter is made from UVFS material, identified by the Mal-1965 material ID. It features a thin lens shape and is coated on both the front and back surfaces with the THo FLH355-10 coating. This coating enhances its transmission characteristics and protects the filter from environmental factors.

According to the vendor's information, the filter has a cut-on wavelength of 350 nm and a cut-off wavelength of 360 nm. This further emphasizes its ability to isolate the desired wavelength range.

The filter is currently in stock and available for purchase through the Thorlabs website, as indicated by its valid weblink status. With its high-quality construction, precise wavelength selection, and versatile compatibility, the FLH355-10 Premium Bandpass Filter is a reliable choice for various optical applications.
