Anti-reflection coatings
Broadband anti-reflection coatings are available on
PCX lenses. Standard BBAR coatings can be applied
to any uncoated optics.
A YAG-BBAR coating
covers 500–1100 nm
and is optimized for
low reflection at both
532 and 1064 nm. The
VIS-EXT BBAR coating
provides < 0.5% average reflectance per surface from
350 to 700 nm.

UV
spectrometer
The UV 470-151
spectrometer incorporates an aber-ration-corrected
concave holographic
grating to deliver f/2.0 performance. A CCD detector
enables operation with a dynamic range of 7200: 1 while
obtaining a signal-to-noise ratio of 1200: 1. The spectrometer’s 190–850 nm spectral range has low stray
light of 0.07% (at 340 nm). Interchangeable slit sizes,
including 15, 25, 50, and 100 µm, are also available.

Fiber waveguide device
A waveguide device that integrates a periodically poled
lithium niobate waveguide with input and output fibers,
a thermoelectric cooler, and a robust metal package is
designed for upconversion of 2000 nm lasers. It converts a broadband laser wavelength to a frequency-doubled signal centered at 1064 nm with very narrow
linewidth.

Galvo
scanner
The Nmark
AGV-HPO galvo scanner
attains single-digit, micron-level accuracy over the field
of view, with resolution of > 24 bits when used with
the company’s Nmark CLS controller. Multiple input
apertures and mirror coatings support a variety of
laser wavelengths. It is available with right- and left-side input apertures for “mirror image” builds.
