Microscope slides are generally 76 mm x 26 mm x 1 - 1.2 mm thick, 76 mm x 50 mm exist but are unusual and expensive.

The cover slips are available in a variety of sizes...22 mm square being most common but 18 mm square, 22 mm x 40 mm, 18 mm x 40 mm are also available. Circular coverslips are available in 25.4 mm, 22 mm, 18, mm 15 mm, 12 mm diameters and a few others exist but are not common.

The material can be glass of several types of different refractive index and some plastics are used as well.

Paper and card masks can be used to space coverslips from slides when thick specimens are being mounted.

The samples shown here may be saved (using a right click) and then printed at 800 x 600 resolution and cut out using a scalpel or craft knife and a steel straight edge.
This type is for coverslips that are 22 mm square.

22 mm square mask

This version is for coverslips that are 18 mm square.
18 mm square mask

This mask can be used with two 76 mm x 26 mm slides to form a sandwich that can be viewed from both sides (ideal for examining the upper and lower surfaces of varroa for bee inflicted damage).
Special mask for
 sandwiching two slides

Paper and card masks can be placed in molten beeswax (in a warming cabinet). The masks can be mated to coverslips and the whole assembly fused together, under a metal weight, providing, of course, that your specimen will withstand the temperature of molten beeswax (63 deg Celsius).
