Olympus UCV for transmittance lamp
Posted: Tue Sep 22, 2020 7:24 am
So an Olympus AX microscope has a slide assembly option that can put what I thought was a beam narrowing two lens assembly in front of a halogen lamp. There is also a U-UCV that dovetails onto the lamp between the lamp and the microscope.
But the AX-UCV seems to diverge the light. Here two laser lines become further apart, two irises are supposed to follow, field stop and aperture stops.
The UCV dovetail adapter does -- I don't know what it is doing.
Both have a large 35mm near the light and 30mm away a 12mm double negative lens. The large one is a meniscus curving out to the lamp for the U-UCV. The AX-UCV does not have so much curvature, but I did not open it too look.
From a user's point of view what is this for? I thought it was to narrow the lamp's beam down. I guess the lamp would have lenses to adjust in it, so would this narrow the beam if the light were not collimated like the two lasers here?
