Ophir Optronics was founded in 1976, as an optical coating company that has grown and diversified into other areas. Ophir employs a highly-qualified staff of over 400 engineers, technicians and skilled workers. Our company products are sold worldwide through a distribution network that includes four fully certified calibration facilities and repair centers. The majority of Ophirs laser measuring instrumentation line is exported and marketed by agents in more than 35 countries around the world, the largest markets being the USA, Europe and Japan. > Sited in an impressive 9,500 sq.m. (102,500...

progress to more powerful systems, especially in the dermatology field, and to introduce diode lasers and intense pulsed light (IPL) sources instead of the traditional gas or solid state lasers. Ophir has developed special equipment that can for the first time measure the output of IPL sources. Regulating bodies such as the FDA in the USA require the manufacturers to have at least one channel of power or energy monitoring in each laser. Ophirs high-quality OEM products provide an extraordinarily efficient answer to this requirement. > Industrial laser customers include both laser...

This section introduces Ophirs wide range of laser measuring instruments for laser users. This general guide, which will assist you in choosing power/energy measurement instrumentation according to your specific needs, also serves as an introduction to other products available from Ophir Optronics. > Ophir standard power and energy measuring heads and displays all use smart head technology. This means that all the configuration and calibration information is stored in a small memory chip inside the smart head plug, so that when the head is plugged into the display the correct power and...

In principle, the reading is not dependent on the ambient temperature since only the temperature difference affects the voltage generated and the voltage difference depends only on the heat flow, not on the ambient temperature. A thermistor is used to compensate for the fact that the thermocouple effect is not exactly linear with temperature (the effect decreases about 10% at the highest operating temperature of Ophir sensors about 80 > o C). The thermistor֒s resistance decreases as the temperature increases. The reduced resistance increases the effective voltage on the amplifier by the...

When measuring a laser with short pulses of tens of s or less, the heat is deposited in a short time and cannot flow during the pulse (see illustration B). Therefore a surface absorber which absorbs the energy in a thin surface layer is not suitable. All the energy is deposited in a thin layer and that layer is vaporized. These limitations catalyzed the development of volume absorbers which have traditionally consisted of a neutral density glass thermally bonded to a heat-conducting metallic substrate. The ND glass absorbs the light over a depth of 1-3 mm instead of fractions of a...

Ophir excimer absorbers are moderately volume absorbing and have excellent absorption in the UV. Having almost complete spectral flatness from 193 to 400 nm, they can also be made in large aperture sizes ideal for excimer lasers. Their ability to absorb well at 10.6 m allows them to be used for CO > 2 lasers too. > Ophir models 5000W, 10K-W and Comet 10K are calibrated using a relatively low power ~ 150 - 300W lasers. Using such low power lasers to calibrate the instrument vs. the high power at which it is used raises the question of calibration accuracy. The following explanation clearly...

The Ophir display unit amplifies this signal and indicates the power level received by the head. Due to the superior circuitry of the Ophir displays, the noise level is very low and the PD300 series heads with Ophir display have a large dynamic range from nanowatts to watts. The PD300 is shown schematically below. The PD300 and PD300-3W have the exclusive patented dual detectors connected back to back which eliminate any signal illuminating both detectors equally (background light). > The sensitivity of various photodiode sensors varies from one head to another as well as with wavelength....

Pyroelectric type sensors are useful for measuring the energy of repetitively pulsed lasers at up to 20,000Hz and are sensitive to low energies.They are less durable and less accurate than thermal types and therefore should not be used whenever it is not necessary to measure theenergy of each pulse and average power measurement is sufficient. The largest markets today for pyroelectric energy heads are the photolithography industry and the medical industry. Pyroelectric sensorsuse a pyroelectric crystal that generates an electric charge proportional to the heat absorbed. Since the two...
