One and hunter thermostat 44760 owners manual two Brewster tubes were also available.
Unfortunately, without an optical bench, this may be very difficult to 2006 honda st1300 service manual achieve.
Thus, a tube with no evidence of a getter spot near the getter electrode (at the end of the cathode bulb) or only a milky deposit, is likely to be dead or on its way out.
To shift the power balance by the observed 5 to 10 percent would not take much of a change in the HR's reflectivity.The beam is boring pure red (632.8 nm, checked with a diffraction grating clean, and reasonably well collimated with a divergence of around.7.Followup: After a year or so of occasionally turning the laser on for a few minutes to check that it still worked, I must have missed a couple months with the result that there was no green output at all.(For some reason, possibly due to the long wire lead to the tube anode, 54K was more stable for tubes with a higher operating voltage than the next choice of 81K.) Both tube voltage and tube current were monitored continuously.The addition of a spark gap surge protector sized to break down at just over the specified starting voltage may represent a prudent precaution when driving large expensive higher power HeNe tubes.This might be excessive caution but it is usually quite easy and painless.(See the section: Major Problems with Mirror Alignment, earlier in this chapter.) I used my trusty little 05-LHR-911 HeNe laser head on an adjustable platform to align mathematics study material pdf its beam through the cards, which had previously each had a hole drilled precisely at the location.However, where the tube has high mileage and died from use and age, it may not simply be a matter of regassing.Dirt and grime may also reduce the insulation resistance.With any significant leakage, these will quickly dominate the spectrum.The ratio of their probability of success compared to your probability of success will approach infinity.
Where the tube is truly 'up to air no discharge will take place, but the weak pink/purple discharge shown will result when the pressure is high enough for O2 and N2 ionization to dominate, and no amount of running will likely be able to clean.
After multiple attempts at cleaning including completely removing the mirror and cleaning (carefully output power on 611.9 nm is only about 1/10th of what it was before.
I initially somewhat confirmed this effect on the 05-LHR-006 tube with HR wedge (and therefore supposedly without HR etalon problems) by alternately heating and cooling only the OC mirror with a blow dryer and damp cotton swab.
(For BD-10 info and a link to one manufacturer, see the section: BD-10 Anatomy and Repair.) Note: For metal enclosed laser heads, it will likely be necessary to remove one of the end-caps and the wire connection to the tube before being able to apply.
They are rare earth magnets with dimensions of about.25".5".375" with the broad faces being the N and S poles.And, it has been suggested that when the swirling clouds are present, it's a good indication that extended run time will result in a successful cure.Even with a small gap in the wire, the power supply may appear to start and run the laser but it's working hard and very likely, erratic behavior will be the result.A hand-held Oudin coil like a BD-10 is ideal for this test and is what I use routinely as a quick check of tubes that don't want to cooperate.The cathode-end mirrors were so far out of alignment that the pointing error could be seen with the naked eye and the reflected spot of the alignment laser wobbled by several degrees as the tube was rotated.This mirror does indeed appear to be highly reflective through the entire visible spectrum.
