65-172 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 671nm
The 65-172 is a Bandpass Filter with a diameter of 25 mm, sourced from the renowned optical vendor, Edmund Optics. This filter is specifically designed for a central wavelength of 671nm, making it ideal for applications that require narrowband transmission in this spectral region.
The filter is characterized by its hard coating, which enhances its durability and resistance to wear and tear. The coating is applied to both the front and back surfaces, ensuring optimal performance from both sides. The coating type is EDM 65-111, a proprietary coating developed by Edmund Optics for enhanced optical performance.
The filter has a thickness of 3.5 mm, providing sufficient mechanical strength for most applications. The geometry of the filter is defined by its circular shape and thin lens design, which minimizes optical aberrations and ensures high-quality imaging.
The physical data of the filter includes a cut-on wavelength of 666nm and a cut-off wavelength of 676nm. This corresponds to a 10nm bandpass, providing a narrow and precise transmission window. The catalog number for this filter is 65-172, and it is currently in stock, as indicated by its weblink status.
