TypBacklight stage polarizer (+ attachment adapter for MS35B/MS36B/RK-10A) designed for use with polarizing model microscopes (AM4113ZT, AM4113ZTS, AM5212NZT or AM4115ZT etc). The "R" variant includes an attachment adapter to connect the backlight stage easily to RK-10A, MS35B and MS36B stands. This easy to use back-light stage with polarizing ability comes with an attachable swing arm target holder for specific placement of objects. The BL-ZW1 is a sturdy and attractive back light stage that is powered through a USB cord or AC Adapter. Adjustment of the polarizer is simply performed by sliding the wheel adjustment located on the front of the stage. Researchers may find that the BL-ZW1 could be an economic substitute to the traditional polarizer microscope. The BL-ZW1 back light stage combined with a AM4113ZT, AM4113ZTS, AM5212NZT or AM4115ZT or other polarizing model has the potential to meet many applications covered by polarizer microscope.
