Affordable Laser Replacement Parts

   We have developed a replacement ceramic reflector that is highly Lambertian and reaches 96% reflectivity.  Our reflector is fully glazed. The glazing process increases resistance to soiling.  The longevity of your reflectors depend on the quality of the cooling water as Vbeam ceramics are bathed directly in the water.  Any contaminates in the coolant water will fuse to the ceramics (and the dye cell as well as the flash lamp/flow tube) and gradually decrease the ceramic reflectivity/light transmission.  As the reflectors and other materials in the head become soiled, higher and higher flash lamp voltages will be required to produce the desired beam intensity. This increased voltage slows your repetition rate and hastens dye degradation/head degradation  as well as places increased stress on many of the electrical sub-systems. Soiling of the coolant water occurs from degradation of the de-ionizer cartridge (should be replaced every year), growth of bacteria (which forms a bio-film), and dust/dirt.  Optimally, you should flush and change the coolant water every 3 months.  You should use reagent grade water and not low grade distilled water from the grocery store as suggested by the OEM (your hospital lab will usually let you have some high quality water).  You should replace the de-ionizer cartridge every year as well.  Lastly, you should rebuild the head parts of the water cooler Iwaki pump after your laser has reached about 1 million pulses to prevent degraded materials from entering the coolant water.
