Microscope Objective Lens, 10x, 0.25 NA, 16.5 mm Focal Length
Model: M-10X
Microscope Objective Lens, 10x, 0.25 NA, 16.5 mm Focal Length
The M-10X microscope objective has a 10x magnification, 0.25 numerical aperture, 16.5 mm focal length, and 7.5 mm clear aperture. It uses a standard RMS thread, 0.800-36. The objective is corrected for a rear conjugate at 160 mm. The lenses are antireflection coated with MgF2 for the visible spectrum. This M-10x objective is suitable for use with either the Model 900 or 910A spatial filters. M- series microscope objective power is based on a 160 mm tube length. MP = 160 mm/f
Ideal for spatial filtering
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.
High Power Laser Application
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.
