Specification Brand : ORBITRANSIT BulletPoint1 : Calibration target for camera, microscope, Projector and other optical devices BulletPoint2 : 100mm*100mm Alumina surface is not reflective, which makes the calibration easy and clear BulletPoint3 : camera calibration chart BulletPoint4 : lens test chart BulletPoint5 : projector/microscope test card BulletPoint6 : Portability: Can be used with or without a microscope. When used without a microscope, it acts as a 20X macro lens. When used with a microscope, the total power = your objective*20X. (For example, LabCam Pro used with 40X objective gives 800X magnification) BulletPoint7 : Compatibility: LabCam Ultra provides 23.2mm, 28mm, 30mm, 30.5mm, and 31.75mm adapters in the box. That covers nearly all microscopes on the market.
