Variable Beam Splitters on Customer Request
Variable beam splitters have a inhomogeneous layer distribution on a square substrate.
The components are used to incorporate two beams in an assembly with a
identical following the last optic in the system. This is impossible with
conventional beam splitters because the different components transmit light
unevenly.
The beam splitters are based on a customer request. The designs depend on
the wavelength: If a variable beam splitter is developed for a wavelength of 532
nm, it does not function at another wavelength. For example, for 1064 nm
designs, transmissions from 45% to 55% and 10% to 70% are available, or for
the wavelength 753 nm transmissions from 4% to 20%.
Two standard sizes are offered: 45 mm x 22 mm and 70 mm x 22 mm. Other sizes
are available but the maximum length of the substrates is restricted at 70
mm.

Model TR1 Tru-Trac
The Model TR1 Tru-Trac® linear measurement solution is a versatile option for tracking velocity, position, or distance over a wide variety of surfaces. An integrated encoder, measuring wheel, and spring-loaded torsion arm in one, compact unit, the Model TR1 is easy to install. The spring-loaded torsion arm offers adjustable torsion load, allowing the Model TR1 to be mounted in almost any orientation - even upside-down. The threaded shaft on the pivot axis is field reversible, providing mounting access from either side. With operating speeds up to 3000 feet per minute, a wide variety of configuration options - including multiple wheel material options - and a housing made from a durable, conductive composite material that minimizes static buildup, the Model TR1 Tru-Trac® is the ideal solution for countless applications.
