Re: Bausch and Lomb

Adding further to the comment regarding the Hemacytometer. The coverslips were designed to be reused after cleaning. They are 0.4mm thick. so the 40x objective usually used for counting RBC, WBC and Platelets needs to have a forgiving working distance. The kit usually came with two coverslips. Regar...

Re: WTB: Leitz mechanical stage for polarizing stage #40, #42 Part Number 553082

One factor you should keep in mind when looking for a circular stage that will be used for Polarization, is the stage center-able, or is the microscope nose piece center-able? Especially if the intended use is as a true PLM. Ideally the nose piece will be center-able because it does not require the ...

Re: Walton/Becket eyepiece graticle Olumpus BX40

The Walton Becket eyepiece reticle is use by Industrial Hygienist for Asbestos Fiber Counting. Keep in mind this is not Asbestos Identification, but counting of particles that are collected from the air.

Re: Leica : FusionOptics

The brain has incredible ways of handling this mix, hence the name Fusion Optics. Leica did exhausti...

Re: 31 15 81 10X W.F. eyepieces

You are probably right. I lose track of time and in the 1980's it was rapid fire M&A with Cambridge. From the AO/Cambridge to the Cambridge/Leitz move only covered three years. Also LKB and a few others were added to the mix on the specimen prep side of the business. In any case the GZ line was an e...

Re: Microscope comparison SM-LUX-POL or American Optical (110?)

I don't recall the system, nor the details, but there was a Leitz system that use an objective in a condenser mount that was used as a condenser. Perfect NA match was the goal nor was there an aperture. Come to think of it, it might have been to be used with a UV source and would allow the transmiss...

I'm not sure of the exact timing, but by the time the SM Lux was in production this was a well ent...

The SM Lux- POL would be a better choice for that application as it is set up as PLM by design and would should offer the types of resources you would need to geological specimens. It addition the optical components should be strain-free....

The other aspect of the 25X eyepiece came about when there was a need to maintain the 4 inch working distance of the StereoStar Zoom microscope and provide a higher mag. Instead of using a 2x aux lens. Also, remember that using the lower zoom or fixed mag on the stereo also provided a greater depth ...

Re: Leica LED Lamp LH111 for DM4000/6000 Wire Pin Out

Sales will not spend time on questions of pin outs, that is the domain of the repair service and you need to get to that part of the operation. You also need to be sure that is where you problem originates. If you have a failure, is it due to the electronics that drive the illumination source,. Wayne

Re: Horace Darwin : Microtome

Hacker Instruments utilized the rocker style Bright microtome well into the 80's. Here is a link as a starting point. http://www.hackerinstruments.com/
The current product offer is probably not using that technology, but they might be able to provide historical information.
