LaserPoint srl

LaserPoint manufactures a wide portfolio of laser power and energy meters able to perform laser measurements with high accuracy. They developed the hard coatings to absorb the laser radiation which allows laser and energy sensors to safely work to the highest level of optical power density. Laser Point consistently supplies its OEM, industrial, medical, and scientific customers worldwide with laser power and energy tools with proven accuracy and reliability.

Technologies include:

Photodiode Sensors

Photodiode Sensors convert incident laser photons into charge carriers, which are afterwards measured as voltage or current. They can detect low light levels and are ideal for low power measurements of CW lasers. Compared to thermal sensors, Photodiodes have a more confined spectral range and lower spatial uniformity.

Thermopiles

Thermal methods of measuring power and energy are those in which radiant energy is absorbed and converted into heat, which generates a temperature rise in the absorber.

• Surface Absorbers consist of a thin layer of materials deposited onto substrates, that can easily transfer heat like high conductivity metals.


• Volume Absorbers gradually absorb radiation as it penetrates the material. LaserPoint’s absorbers can withstand peak powers of 100GW/cm² and energy densities up to 30J/cm².


• Super Hard Coating withstands more than 12KW/cm² in CW operation, with an effective applied power of 1KW of YAG laser, or 40J/cm² with laser diodes peak powers of 3.2 KW @1 ms!

High Speed Thermopiles

High speed thermal sensors measure the energy of single laser pulses with repetition frequencies up to the MHz range. The the sensor works in a broadband spectrum, from UV to THz and operates in a broad range of incident average optical power densities of the laser radiation, without needing to adopt precautions.

Calorimeters

LaserPoint’s instrument based on calorimetric measurement, can safely face the high-power densities of today’s lasers. The presence of Super Hard Coating as radiation absorber helps achieve a higher absolute power measurement capability with compact footprints associated to a higher damage threshold.
