Initially, Basler ac2500-14um Updated to Basler ac3800-14um

Basler CMOS camera >> c mount thread adapter >> 1x extension tube >> zoom control, coaxial LED light holder >> 25% reducer added at the very bottom

Hi All, If we install the MVLX075L 0.75X Magnifying Lens. We will go from a working distance of 92mm to 113mm. That gives us an extra 21mm distance. The magnification of the zoom lens will still be fine but we will have to zoom in a little more. The MVL6X05L 0.5X Magnifying Lens would increase our w/d even more to 175mm but I am afraid we will start losing image brightness from the lighting system at this distance. I would recommend we go with the MVLX075L from Thorlabs.

• Kinematic mount to optical breadboard attached to z-stage
• Lights: two LEDs (spotlights) mounted externally, one mounted via the coaxial illuminator (and therefore casting light in the optical path)
• Basler ac3800-14um
• c mount thread adapter
• 1x extension tube (MVL6X3Z lens - 6.5x zoom lens with coaxial illuminator)
• Zoom control (part of the extension tube)
• MVLX075L 0.75X Magnifying Lens (needed longer working distance)

Working distance is 11.2 cm.

AT 1.5x ZOOM:

• Field of view ~ 4.3 mm by 6 mm
• 1.58 microns/pixel
