It is a pleasure to work with PGL as they consistently respond to our unique requirements and deliver superior products. — Dr. Thomas Metzger, TRUMPF Scientific Laser, Germany

Adjust the eyepieces for the correct interpupillary distance to suit you. Do this by moving the eyepieces closer together or farther apart until a single field of view is observed (B). Now, set the Dioptric adjustment rings on both eyepieces to the zero position (A).

A low power or stereo microscope typically employs objective lenses of 50x or less. It is used to view specimens that are visible to the naked eye such as insects, crystals, circuit boards and coins.

Diffraction gratings are critical components for most Chirped Pulse Amplification (CPA) laser systems. There are many different grating types (metal, all-dielectric, and hybrid metal-dielectric reflection gratings, as well as transmission gratings), and equally as many trade-offs relating to diffraction efficiency, spectral and angular bandwidth, polarization, laser-induced damage threshold (LIDT), and temporal dispersion, to name a few. Choosing the right grating for a given laser system can be very confusing. In this webinar we will describe how you can make the best grating selection for your laser requirements.

Diopter adjustment ring that allows for the possible inconsistencies of our eyesight in one or both eyes. Binocular microscopes also swivel (Interpupillary Adjustment) to allow for different distances between the eyes of different individuals.

Adjust the microscope down to the lowest magnification using the Magnification adjustment knob. The image could be slightly out of focus.

Turn on The Transmitted/Oblique illuminator. Place a small solid specimen onto the stage such as a card, coin or any other flat, detailed object.

PGL's innovative manufacturing techniques allow us to push the boundaries of what is normally possible in grating manufacturing, which has allowed us to deliver unique high power laser capabilities. — Trevor Winston, Rutherford Appleton Laboratory, UK

Working Stage is where the specimen to be viewed is placed. Pole and track stands have simple stages since lower magnification powers require less subtle movements than high power microscopes.

Transmitted Illumination Since most specimens examined on a stereo microscope are opaque, a top light (Transmitted Illumination) is used to shed light on the specimen. Some stereo microscopes also include a bottom light (Incident Illumination).

Eyepieces or Oculars are what you look through at the top of the microscope. Typically, standard eyepieces have a magnifying power of 10x. Optional eyepieces of varying powers are available, typically from 5x-30x.

As in a compound microscope, there are two optical systems in a compound microscope: Eyepiece Lenses and Objective Lenses.

Use the Magnification adjustment knob to set the highest magnification. Bring the image into focus with the focusing knob.  Center the image on some clear point of detail on the specimen.

Stereo microscopes are increasingly modular. This means that the same head can be used in conjunction with different focus blocks and stands. For example, Microscope.com offers a range of pole stands, track stands and boom stands.

Objective Lenses are the primary optical lenses on a microscope. In a low power microscope, they provide fixed magnification or zoom magnification. Zoom magnification is typically offered in a Greenough design or with a Common Main Objective.

Do not adjust the focus with the focusing knob.  Adjust the focus for each eye separately using the eyepiece Dioptric adjustment rings.  Your microscope is now "parfocal". This means that as the microscope is zoomed from high to low magnification the image will stay in focus throughout the entire range. Each individual will have a different setting.
