About this product
Dimension: 45mm (1-3/4") in diameter approximately. A typical use would be a blue filter when using low levels of light in a brightfield application. (Like dry layer blood analysis.) When low levels of light are used, you usually get a yellowing effect because the lamp is turned low. The blue filter brings the light back to a more natural white light.
