Our microscope objectives are broadband AR coated and designed for diffraction limited performance across the entire visible spectrum. This allows collimated beams from lasers such as HeNe, Argon, or frequency double Nd:YAG to be focused to a small spot for spatial filtering. In spatial filtering, a laser source is focused to a diffraction limited airy disk spot pattern. A pinhole is placed at the focal plane sized such that only the central lobe of the airy disk may pass through. This removes undesired higher spatial frequencies to produce a clean uniform output beam. Please see our Three-Axis Spatial Filters and our space-saving Compact Five-Axis Spatial Filters.

The M-20X is highlighted here in a laser engraving example. This example highlights the fact that these objectives can be used without issue. Unfortunately there is no specific data for actual laser damage. For any high power application, due to the sensitive nature of the environment, the level of cleanliness, and laser power homogeneity, the objectives cannot be guaranteed to perform without damage.

DOF is a range of object distance, which the image appears to be sharp and focused. Also a parameter describing the distance of imaging side ( sensor side) is called depth of focus. Tolerable level of blur is called Permissible Circle of Confusion, or Permissible COC.This represents the smallest diameter of a bundle of rays when being focused on an image plan. The diameter of Permissible COC will be defined by each application, pixel size of camera and the person who actually measures. The amount of DOF shown in this catalogue is given by:

The objective lens is the primary lens that captures light entering an optical device, such as a telescope, microscope, camera, binoculars, etc.

Our M- microscope objectives are corrected for a rear conjugate at 160 mm, and this family is the most popular family in the microscope objective offering. The M- series is currently available in a range of powers from 5x to 20x.  If cost is an issue, the MV- series is the economical choice for standard laboratory applications.  Please see Economy Microscope Objective Lenses.
