The AvaSpec-HS2048XL is an instrument designed for highly sensitive applications in which a high resolution is not essential. The HS optical bench from Avante with a full 0.22 numerical aperture is included. The CCD detector is back-thinned and has 2,048 pixels. The wavelength range is 200-nm to 1,160-nm, and the resolution ranges up to 10-nm, depending on the configuration. The stray light is <1%. Integration times go as low as 2 microseconds thanks to the electronic shutter. A detector collection lens can be combined with a larger core fiber to improve sensitivity up to 60%. An interface with a high speed 2.09-ms/scan USB 2.0 port and 432-ms/scan RS-232 is included. Additional features include a signal to noise ratio of 450:1, integration time of 2 µs - 600 second, and various digital I/O connectors.
