TECHSPEC Hard Coated OD 4.0 5-nm Bandpass Filters from Edmund Optics Inc. provide the high transmission and deep rejection necessary to isolate narrow spectral regions for use in a wide variety of applications.
The devices exhibit a narrow, 5-nm full-width half max (FWHM), making them ideal for laser line cleanup applications. They allow for improved signal-to-noise ratio when compared to those achievable with wider band filters and may also be used in elemental or laser line separation, chemical detection, or fluorescence applications. These precision bandpass filters offer 80-50 surface quality and center wavelengths from 343 to 1064 nm, covering second and third harmonic Nd:YLF and Nd:YAG lasers, diode lasers, and HeNe lasers. TECHSPEC Hard Coated OD 4.0 5-nm Bandpass Filters provide a blocking wavelength range of 200 to 1200 nm and >85 percent minimum transmission.
The filters are manufactured with durable hard coatings to minimize filter degradation and increase transmission. With a variety of UV, VIS, and NIR laser lines available, these devices offer steep blocking and transmission slopes to achieve the highest performance in a wide variety of demanding applications.
