FEL1350 Dia:1 in Longpass Filter; Cut-On Wavelength: 1350nm

The FEL1350 Dia:1 is a Longpass Filter manufactured by Thorlabs, a leading vendor in the optical industry. This filter, characterized by its circular base shape, is designed with a diameter of 25.4mm and a thickness of 3.5mm, making it compatible with a wide range of optical systems.

The filter's primary function is to allow the transmission of light with wavelengths greater than 1350nm, while blocking or significantly reducing the transmission of shorter wavelengths. This is achieved through the application of a specialized coating, denoted as 'tho fel1350' on both the front and back surfaces. The 'tho fel1350' coating is a proprietary technology of Thorlabs, ensuring high-quality performance and durability.

The FEL1350 Dia:1 is categorized as a Thin Lens, indicating its ability to focus or disperse light. This feature adds versatility to the filter, enabling it to serve dual roles in optical systems, both as a wavelength-selective element and as a lens.

According to the vendor's website, the FEL1350 Dia:1 is currently in stock, indicating its availability for immediate purchase and delivery. The product's catalog number, FEL1350, can be used to access additional information or place an order directly from Thorlabs' website.
