39-382 50 mm Dia. Hard Coated OD 4.0 5nm Bandpass Filter; t=3.5 mm 1064nm

The 39-382 is a Bandpass Filter with a diameter of 50 mm, sourced from the reputable optical vendor, Edmund Optics. This filter is specifically designed for a central wavelength of 1064 nm, making it suitable for various applications that require precise wavelength selection.

The filter is characterized by its hard coating, which enhances its durability and resistance to wear and tear. The OD (Optical Density) is 4.0, indicating a high level of attenuation for wavelengths outside the passband. The passband itself is 5 nm wide, providing a narrow and precise range for the transmitted light.

The filter's geometry includes a thickness of 3.5 mm, and it is cut on at 1061.5 nm and cut off at 1066.5 nm. This precise cutting ensures the filter's functionality within the desired wavelength range. The coating on both the front and back surfaces is EDM 39-337, further contributing to the filter's performance and longevity.

The shape of the filter is thin lens, making it compatible with various optical systems. The catalog number for this item is 39-382, and it is currently in stock, as indicated by its weblink status. For more information or to make a purchase, users can visit the provided weblink.
