Olympus PLN 20X Objective

Anti-reflection (AR) coatings are applied to optical components to increase throughput and reduce hazards caused by back-reflections.

Optical coatings are used to influence the transmission, reflection, or polarization properties of an optical component.

Learn about the different components used to build a microscope, key concepts, and specifications at Edmund Optics.

Multiphoton microscopy is ideal for capturing high-resolution 3D images with reduced photobleaching and phototoxicity compared to confocal microscopy.

This comparison of the performance of aspheric, achromatic, and spherical PCX lenses in different situations reveals the ideal use cases for each type of lens.

Confocal microscopy provides high resolution, elimination of out-of-focus glare due to spatial filtering, and reduction of light-induced damage to the sample.

Microscopes are used in a variety of fields and applications. To understand how resolving power, magnification, and other aspects work, read more at Edmund Optics.
