For transmission measurements of samples of various sizes and thicknesses, the variable collimating lens holder is the perfect tool. The vertical bars can be adjusted to samples up to 160 mm thick. The base is made of anodized aluminum and features adjustable mount bars. Each bar has four 3/8”-24 threaded holes for COL-UV/VIS collimating lenses. Adjusting the bars is easy, simply loosen the screws and slide.
Two COL-UV/VIS collimating lenses are included with the variable collimating lens holder.
