NEW PRODUCT: Generic 4X PLAN Infinite Microscope Objective
This is a 4X PLAN infinite microscope objective. It has NA of 0.1 and requires 180mm tube lens. Effective working distance is about 19mm. It is an excellent choice to start doing extreme macro using an objective.
Because it is an infinite objective, magnification can be varied by using different focal length tube lens. For example, when a 70-300 zoom lens is used as tube lens, when zoom is set at 300mm, magnification is 4x300/180 = 6.67x. It has been tested to have vignette if tube lens is less than 180mm.
It will be available on the site soon, and we will also add it to some sets of our stacking rail range of the RS-90
