Launched beam profiler suitable for wide-range wavelength beam measurement from visible to near-infrared region

Kokyo, Inc. (Representative Director: Kazuhiko Sumimura, Headquarters: Kyoto City, Kyoto Prefecture) is pleased to announce that newly developed LHB-VISNIR-GigE and LHB-100-VISNIR-GigE, which have different light-receiving surface dimensions, are compatible with the “visible light to near-infrared wavelengths”, will be released from 2021/1/29 (Fri). LaseView-LHB series that can measure, analyze, and evaluate the beam profile of large-diameter, high-power laser light with a single unit.

The new product is positioned as a sister product with improved functions based on the two near-infrared light models LHB-NIR-GigE and LHB-100-NIR-GigE currently on the market, and has a wider range of visible light to near infrared light than before. Beam measurement and analysis in the range can be performed with a single device. In addition, the number of sensor pixels*1 and optical resolution*2 have also been improved, enabling measurement, analysis, and evaluation of beam quality under highly accurate and stable conditions.

Features of the previous LaseView-LHB series

  • Easy measurement of beam profile and beam diameter.
  • Large-diameter laser measurement is possible (1 mm to 100 mm).
  • Laser measurement from low output to high output is possible (1 mW / cm2 ~ 100 W / cm2).
  • With speckle (glittering bright and dark spots) reduction function.
  • With beam profiler with M2 platform software (LaseView).

New product features

  • Compatible with visible to near-infrared beam light (400 to 1700 nm).
  • Improved sensor pixel count *1 and optical resolution *2.
