This magnifier is composed by two optical glass lenses, which are cemented together. The image seen through this lens is free of color and gives sharp contours so that no vague lines will be found throughout the entire image field.
With a solid red wood handle and a red mark at the base of the lens frame, this reminds you to use the face having this red point upwards.
The lens diameter is 37mm and the magnifying power is 4x. Both faces are purple coated and they measure 39 x 15 x 155mm., Weight 73g
