Lens of the laser wavelength absorption increase will cause uneven heating leads to reflection of the lens, the refractive index changes when the laser wavelength transmitted or reflected from a high absorption of the laser power distribution of the lens so that the lens center high temperature non-uniformity, edge temperature is low, This change produces a lens effect, said optically. Due to the high absorption of lead pollution caused by the lens thermal lensing produces many problems. Lens substrate irreversible thermal stress, when the beam propagation power loss generated by the lens, the focusing spot position of partial movement, the plated layer and so can lead to premature failure of the destruction of the lens. For lenses exposed to the air, when we do the clean-up, clean-up lenses often do not follow the requirements and considerations, casually drawn, the results will cause new pollution even scratch the lens, causing irreparable damage. So based on years of experience that: no matter what kind of optical lenses clean is the most important, a good cleaning habits to carefully clean the lens, you can reduce or eliminate related to pollution caused by man-made causes. Such as fingerprints and saliva flowers. As a common sense when operating a hand to the optical system, laser laser machine, regardless of the cleaning, demolition Jiang million laser laser machine parts repair, installation should bring finger or medical gloves, to always keep the lenses clean follow the requirements and precautions Product Dimensions: 119.9mm × 91.0mm support Windows 98 / Windows 2000 / Windows 7 / XP operating system default Road sixteen high-speed precision D / A channel control galvanometer optional third, four sixteen high speed and precision D / A channels; YAG laser can be controlled according to the needs of power, or as an aspect of the dynamic focus control, or other required D / A control (502P + cards have this feature) default nineteenth-way switch output (TTL level, which DO12-DO15, four with optical isolation), can control the laser power, Dongguan Humen laser laser machine maintenance, sound and light power, the axis of rotation, the two-dimensional table, solenoid valves and other laser printing system with optional auxiliary equipment Rd switching output (TTL level, DO19-DO23, Rd with optical isolation), can control the laser power, sound and light power, the axis of rotation of Dongguan Changan laser laser machine, two-dimensional table, solenoid valves, etc. Laser Printing System Auxiliary equipment (502P + cards have this feature) Optional eight digital inputs (TTL level, DI16 ~ 23, eight-band optical separation) can be accessed by foot and other auxiliary equipment input signal (502P + cards have this feature) Default sixteen digital inputs (TTL level, DI0 ~ 15, Sixteenth Street with optical isolation) can be accessed by foot and other auxiliary equipment all the way to the PWM signal input signal default, the frequency and duty cycle can be set in software set can be used to control the acousto-optic modulator and CO2 lasers default all the way 32-bit hardware timer can be realized in software with the next flight marking WARNING: 502P boards are not hot-pluggable, otherwise it will burn this card NOTE: The above contains selected The feature is available only with words 502P + card, the card is no such function Jiang million ordinary laser laser machine laser laser machine parts repair _ _ small family provided by the City of laser Laser Equipment Co., a small family.
