FGL695 Dia:25 mm RG695 Colored Glass Filter; 695nm Longpass

The FGL695 Dia:25 mm RG695 Colored Glass Filter is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of advanced optics. This filter is designed with a longpass characteristic, specifically at 695nm, making it ideal for applications that require the blocking of shorter wavelengths while transmitting longer ones.

The filter is manufactured from n-bk7 Schott, a renowned optical glass material known for its excellent optical properties. It features a circular geometry with a diameter of 25mm and a thickness of 2mm, ensuring robustness and stability in various optical setups. The FGL695 is coated on both the front and back surfaces with Thorlabs' proprietary coating, enhancing its performance and durability.

The FGL695's physical data indicates a cut-on wavelength of 695nm, meaning it begins to transmit light at this point, and continues to do so for longer wavelengths. The cut-off wavelength is 0nm, signifying that it blocks all wavelengths shorter than 695nm. This makes it an excellent choice for applications that require the isolation of specific wavelength ranges.

In terms of shape, the FGL695 is designed in a Thin Lens format, which can be beneficial in certain optical configurations.
