Viktor,
I use a Yongnuo YN560EX (GN 58) with a cube beamsplitter in this setup: viewtopic.php?p=224611#p224611
I don't recall having used more than 1/8 power setting for 40X 0.70 DIC, although our systems are very different

Pentax Auto-Bellows repair parts
My Pentax Auto-Bellows suffered an accident and one of the dovetail shaped nylon sliders broke beyond repair. I have a spare bellows but it has one of those parts partially cracked. Knowing its age very likely the plastic has turned rigid and brittle. Does anyone know a source of parts replacement? ...

Re: Light Source for BH2 BHTU
Dave, could you compare the convenience of the Saul's and Retrodiode's illuminators for continuous illumination in the same microscope? I'm interested in light intensity, regulation, light quality and mainly ability to set Kölher. Just curiosity because I have both continuous and flash illumination ...

Re: Amscope 4x extension distance
For objectives marked 160/ this distance is 150mm (this is due to the classic microscope design: the "primary" image projected by the objective is expected at the eyepiece aperture placed 10mm below the end of the microscope tube) Anyway, a 4X objective is pretty tolerant for changes in this distanc...

Re: Birefringence Terminology
Optical activity can be demonstrated in solids as well as solutions. D and L rotary quartz, for example. Sure, although I think that this refers to different causes: organic molecules chirality is caused by the spatial asymmetry of their molecular structure while in quartz this is just impossible a...

Re: Birefringence Terminology
Leonard, I'm not able to solve your question because of lack of experience with Oxalate and not enough knowledge, but maybe could help to clarify few points - Chirality demostrates in solution (often not easily without a precision polarimeter), not sure up to what point it could be related with bire...
