The 871 Series Laser Wavelength Meter uses a proven Fizeau etalon-based design to measure the wavelength of both pulsed and CW lasers that operate from 375 nm to 2.5 μm.

The innovative Optran® UV NSS is a solarization-resistant optical fiber with a hermetic carbon layer ideal for spectroscopy, medical diagnostics, and laser delivery systems.

The 671 Series Laser Wavelength Meter uses proven Michelson interferometer-based technology to accurately measure the wavelength of CW lasers that operate from 375 nm to 12 μm.

Laser Components' double beam splitter has combined both a beam splitter and a polarizer into one component, saving space in setup and time in servicing. This beam splitter consists of a combined beam with the wavelengths 1030 nm and 515 nm split in such a way that 50% of each of the beam components is reflected or transmitted, despite the different polarization of the two wavelengths.

The HP60A-15KW-GD-QBH-MET-D0 from Gentec-EO is a high power detector for laser power measurement up to 15000 W, including a QB/QBH fiber adaptor.

The F150(200)A-CM-16 is a thermal power/energy laser measurement sensor with a high damage threshold for high repetition rate pulsed lasers. It has a 16mm aperture and can measure power from 300mW to 150W continuously and to 200W intermittently. 

G&H’s Superpolishing process delivers Scratch-Dig of 5-2, less than 0.5 Å of surface roughness, and zero defects at 300x magnification for ring laser gyroscope (RLG) mirrors, R&D applications, short wavelength and ultrafast lasers.

The YLR-U Series incorporates the latest advancements in IPG world-leading industrial pump diode packaging technology and are the only hermetically sealed mid-power lasers on the market that can operate in extremely high humidity environments up to 90% relative humidity. Remote control options include Analog, RS-232 or Ethernet, and built-in self-diagnostics with internet connectivity.
