The FGB67S is a 2 in x 2 in Square BG36 Colored Glass Bandpass Filter, designed for use in the 900-1375nm wavelength range. This filter is sourced from Thorlabs, a renowned vendor known for their high-quality optical components.
The filter is made from N-BK7 Schott, a popular optical glass, and features a rectangular base shape. It has a thickness of 2mm, making it a suitable choice for applications that require a thin, yet robust optical element. The FGB67S is designed with a Thin Lens shape, which can be beneficial in certain optical configurations.
The FGB67S has a cut-on wavelength of 900nm and a cut-off wavelength of 1375nm, making it ideal for applications that require narrowband filtering in the near-infrared spectrum. The filter's coating, both on the front and back, is designated as 'tho fgb67'. This coating likely plays a role in enhancing the filter's performance within its specified wavelength range.
According to Thorlabs' website, the FGB67S is currently in stock, indicating that it is readily available for purchase and use in your optical systems. For more information, including pricing and detailed specifications, please refer to the provided weblink.
