A spectroradiometer JETI specbos 2501-HiRes or spectraval 1511-HiRes can be used for the measurement of RGB laser projection.

The white signal of a RGB Laser projector consists of three narrow signals of red, green and blue, which form a large and impressive color gamut. It is helpful to use a spectroradiometer with a higher optical resolution for the calibration of such projectors. Therefore, JETI offers a special version of specbos 2501 and spectraval 1511 with an optical resolution of 2 nm (HiRes) instead of 4.5 nm. The application of such device allows a color setting with a higher matching to the visual impression.

Which device should I opt for?

• Applications
  Both devices are designed for the measurement of RGB laser projectors and displays. The specbos 2501-HiRes can measure laser projection and displays, as well as being suitable for the calibration of broadcast monitors and color adjustment of digital projectors.
• Stand-alone Capability
  The spectraval 1511-HiRes can be operated independently of a computer because it has an integrated display and a SD card drive.
• Optical Resolution
  Both devices have an optical resolution of 2 nm. The specbos 2501 has this resolution when equipped with the HiRes add-on.
• Wavelength Range
  Both devices have a wavelength range of 380 ... 780 nm.
• Interfaces
  The spectraval 1511-HiRes utilizes USB and Bluetooth interfaces. The specbos 2501-HiRes uses USB-C and Bluetooth, but can optionally use LAN or PoE (Power over Ethernet).
• Light Receiving Element
  The spectraval 1511-HiRes uses a CCD line array with 4096 pixels. The specbos 2501-HiRes uses a back thinned CMOS/CCD array with 2048 pixels.
• Power
  The spectraval 1511-HiRes can be powered by batteries. The specbos 2501-HiRes is powered by USB but can be powered with PoE if it has the LAN add-on.
