CSlaser | CTlaser Series Infrared Thermometer
The infrared thermometers of the optris CSlaser/CTlaser series consist of an innovative double laser sighting, in contrast to many IR thermometers with single lasers which only mark the center of the spot. The two laser beams follow the infrared optical path to mark the position of the measuring field at any distance. At the focus point both lasers are crossing – this greatly supports an exact alignment and reduces measurement errors. The infrared thermometers of this class are mainly used in industrial areas as well as in research and development. Small measurement field sizes are of great importance for precise temperature measurement. A number of different focus versions allow a flexible adjustment for the different applications.

Diamond-like Carbon (DLC) Foils
An intense laser beam is used to evaporate carbon from a graphitic sputter target. In the process, the graphite structure of the source material is converted into nano-particles, which deposit on prepared substrates as diamond-like carbon. The properties of these unique carbon foils make them useful in a variety of applications, in particular beam stripping, as backings for accelerator targets or x-ray attenuators.

*Beam Profiling For 266nm To 3000µm
Unlike a power meter that measures average or instantaneous Watts or Joules of the overall laser beam, knowing how the power is distributed within the beam is equally as important. As an example, if you want to cut something the power should generally be focused in the center of the beam to concentrate the power density in a very small area but if you were trying to weld something with all the power in the center you would poke a hole in the weld; requiring the power to be equally distributed as in a top hat profile.

Laser Heads
The laser head is the source of the laser beam used in all laser motion and position measurement systems. The primary difference between laser heads is in the velocity, reference frequency and optical output power. Other considerations are size, heat dissipation, and input power requirements. Which laser you choose depends primarily on the application in which it will be used. For example, semiconductor lithography systems typically have faster moving parts (stages), and therefore need higher velocities than machine tool applications.

The Keysight 10735A Three Axis Interferometer is used in multiple axis applications where linear and angular control of the stage is required. It combines in a single package the functionality of an optical bench with multiple beam benders, beam splitters, and three interferometers. The interferometers split an incoming laser beam into three beams to measure linear distance, pitch and yaw, or linear distance, roll and yaw. Three linear measurements provide the basis for calculating two angular measurements. The inherent beam parallelism ensures that there is essentially no cosine error between the three measurements and also ensures angle accuracy for pitch and yaw measurements.

Pulse Characterization Sensors
Pulse Characterization Sensors provide the ability to see and measure the temporal characteristics of pulsed and CW laser beams. Ophir Fast Photodiode Detectors are designed to convert optical signals into electrical signals which are then measured with third-party instrumentation such as oscilloscopes and spectrum analyzers. Accessories are available to connect to IS6 integrating spheres or fiber optic cables. Attenuating filter accessories are also available to increase their dynamic range. Different models offer silicon, UV enhanced silicon and InGaAs PIN photodiodes, covering a combined spectral range of 193 nm to 1700 nm. Rise times range from 25 picoseconds to 3 nanoseconds. The fast rise times are achieved by an internal reverse bias voltage circuit. Power is supplied by internal batteries and/or an external power supply depending on the model. Detectors should be connected to a 50Ω impedance in order to maintain their nominal rise times. They can be connected to higher impedance loads, but this will result in a significant increase in the rise time. If higher output voltage is required, it is recommended to connect the detector to a trans-impedance amplifier with an Input impedance of 50Ω
