Just select Zygo Test Report from the drop down box at the top of the listing and we will test the optics in house and provide a full 2 page report with your scope. We are using the very latest Zygo MX software to provide a more detailed report compared to other standard reports. I've got the plumbing part of the cooler worked out, but can't find the right fan to push the air through. The SCT Cooler has a filtered air intake and other design features whcih minimize the possiblity of dust infiltration and direct the air flow away from the internal optical surfaces. PDSA will never exchange or sell your information to another organisation for their own marketing purposes.

These tube currents cause distortion similar to the wavering mirages you might see on the road on a hot day. Until the telescope tube and the optics it houses reach a temperature close to that of the surrounding environment, it will not give the best images. The downside is that it will increase the coke yield, reducing the liquid product yields, but at increased conversion.These are values which ideally would be at 0 but as our test optics are all curved lenses, there will always be astigmatism and coma present. As mentioned above, the typical CPU fan doesn't have enough umph to push the air through the narrow 3/4 pipe into the scope. Once the measurement has been taken, we are provided with a series of results that show the optical quality of the surface plus other information.

Generally, the higher the Strehl ratio, the lower the Astigmatism and Coma meaning a better image quality from your instrument. Had a feral cat trying to get warm near my home this past cold winter, but couldn't entice it/him/her to enter the insulated container. Car window sunshade with a cool design three big cats , to keep your car cool in the summer while parked.Throw that in the blender with some ice, and it's said to bring out the drinker's "power," in a very biblical sense, if you know what I mean. Within the interferometer is a calibrated laser that is pointed through the optical test surface, then onto a high quality reference sphere, then back through the test subject then to an internal camera which gives us the measurement on the screen.
