AmScope PH40X 40X (Spring) PH Achromatic Microscope Objective

AmScope 40X (Spring) PH Achromatic Microscope Objective

• This 40X phase-contrast objective lens can be used to enhance contrast invisible to the eye when used with an appropriate condenser and phase ring.
• Intended for biological applications, the lens is corrected for 0.17mm cover-slips.
• The spring-loaded nosecone helps to prevent impact damage to slides and the lens.
• Designed for compound microscopes which use DIN standard lenses with RMS thread and 45mm parfocal distance
• Achromatic corrections provide better color accuracy and resolution.

This is a 40X achromatic phase-contrast objective lens for DIN-standard microscopes. An integrated phase-ring enhances contrast of invisible details when used with a compatible condenser and phase annulus. As light passes through a specimen with varying refractive indicies, otherwise invisible details can be imaged by manipulating the phase of light. Intended primarily for biological applications, this lens is designed to work with microscopes using 160mm tube-length and 45mm parfocal distance. Achromatic correction provides improved color accuracy and resolution. The spring-loaded nosecone helps to prevent impact damage to slides and the lens.
