Newport MKS Microscope Objective Lenses

Newport Microcsope objectives are ideal for collimating and focusing beams in the visible spectrum. Common applications involve focusing laser beams or spatial filtering. Cleanly colllimate and focus beams Rear conjugate corrected objectives Ideal for use in spatial filterting Visible AR coated Features 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. Finite Conjugate Objective Selection Our MV- and M- microscope objectives are corrected for a rear conjugate at 187 mm and 160 mm, respectively. The MV- series is the economical choice for standard laboratory applications. The M- series is available in a range of powers from 5x to 60x, either individually or as a complete set.
