Bristol Instruments Inc.’s 821B-IR laser wavelength meter is for researchers who need to know the exact wavelength of their pulsed infrared lasers and optical parametric oscillators. The wavelength meter operates from 1.5 to 5 µm. Proven Fizeau interferometer-based technology is used to measure the absolute wavelength of pulsed and continuous-wave lasers to an accuracy as high as ±0.004 nm. To achieve reliable accuracy, the system is automatically calibrated with a well-known wavelength standard. A measurement rate of 200 Hz and other features allow for convenient...See full product
