FARUM, Denmark, Jan. 21, 2011 — Ibsen Photonics has launched the Rock UV line of industrial grade robust OEM spectrometers for the 200- to 400-nm wavelength range. They typically enable four times higher optical throughput than traditional spectrometers due to a near on-axis beam geometry in the optical bench and the use of proprietary and highly efficient fused-silica transmission gratings. The athermal instruments are supplied in three standard models using either a low-cost CCD, a high-sensitivity back-thinned CCD for low-light applications, or a low-noise CMOS line array sensor for applications requiring a high dynamic range and a high signal-to-noise ratio. The OEM-friendly design enables adaptation of the detector and electronics to allow customers to re-use existing electronics and software designs. All three models have a numerical aperture of 0.22, minimum resolution of 0.75 nm FWHM, grating efficiency >40% and stray light <0.03%. The RSV-305 and RSV-145 use a Hamamatsu CCD and a Hamamatsu CMOS sensor, respectively, and the RSV-300 uses a Sony CCD. All have a USB 2.0 and an RS-232 interface, operate from -10 to 45 °C and produce temperature drift of <0.01 nm/°C. All measure 110 × 105 × 45 mm. A range of input slits accommodate customer requirements for optical resolution. The devices are based on a modular design whereby customers can choose to buy a complete spectrometer, a spectrograph or just a spectrometer grating. The instruments can be fitted to almost any detector and electronics, and custom configurations are available.
