The PZ620T is an indispensable instrument for mineralogists, pathologists, and any laboratory that needs a polarizing microscope that delivers quality and versatility. The microscope is equipped to handle polarization for transmitted and reflected illumination, with a rotating stage and a Bertrand lens for in-depth mineral analysis. High-power incandescent illumination and strain-free optics ensure optimal image quality for both orthoscopic and conoscopic observation over a large magnification range with seven included objective lenses.
Viewing Head
The microscope's head is designed for precision and comfort. The super-widefield optics provide a larger field of view so you can see more specimens at any magnification. Compensation-free Siedentopf interpupillary adjustment allows any user to properly align the oculars without readjusting focus. For astigmatism or asymmetrical vision users, the left ocular can be adjusted to fine-tune focus. The photo port is equipped with a 23mm tube for attaching cameras with compensating lenses and is height-adjustable to match focus with the eyepieces. The port is compatible with YX series C-mount adapters which can attach directly to C-mount cameras without a compensating lens - ideal for 1" format sensors. The head is set to a 30° incline which is ideal for viewing from a standing position, and it can be rotated 360°.
Bertrand Lens
The Bertrand lens allows the user to quickly switch between normal orthoscopic and colonoscopic observation. This is required to shift to the rear focal plane for proper alignment of the aperture diaphragm and to observe interference patterns created by minerals under polarized light. The lens assembly has a slot for the included first-order, quarter-wave, and quartz-wedge retardation plates.
Optics
The infinity-corrected optical system eliminates optical errors when using filters and other in-line components, which is of paramount importance in polarized-light microscopy. The quintuple objective turret provides instant access to 5 magnification levels to efficiently move through magnifications from 50X to 1000X. Seven objective lenses are provided ranging from 5X to 100X, with both oil and dry 100X lenses. The turret's reversed orientation provides more working room above the stage. These high-quality lenses are strain-free to ensure accurate observation under polarized light, with plan-achromatic corrections to improve resolution and field flatness for edge-to-edge sharpness. Each objective mount can be independently centered to ensure proper alignment.
The Stage
The stage is designed for precise sample placement, with full stage centering and a dual-axis mechanical caliper which can accommodate varying specimen sizes. Once centered, the specimen can be rotated to locate its axis and tested for birefringence. The sub-stage polarizer can also be rotated to avoid stage movement when working with specimens with weaker birefringence.
Koehler Transmitted Illumination
Built on Koehler illumination principles, the sub-stage lighting provides evenly distributed light for optimal contrast. The rear-mounted 100W incandescent light source provides 100 CRI illumination with ample brightness for contrast-enhancement methods like darkfield. The lower color temperature of the halogen light source causes less eyestrain compared to high-Kelvin LED. The light condenser uses a swing mechanism for optimized lighting at both high and low magnifications, with an NA0.25 setting for full coverage at extremely low magnifications. An iris diaphragm allows you to adjust the aperture to optimize contrast and depth of field. The condenser holder has an integrated, rotatable polarizer for diascopic polarization. It uses rack-and-pinion height adjustment for precision control and is central for proper alignment. The condenser is top-mounted for easier replacement when working with additional condensers. The illuminator's field lens provides an iris diaphragm to control light spread, optimizing contrast and definition in specimen features.
Koehler Reflected Illumination
The top illuminator also uses a 100W incandescent light source to provide ample light for use with polarization. Adjustable aperture and field diaphragms offer precise control over the light field for improved contrast and edge sharpness. A removable polarizer board provides polarization for reflected illumination. The analyzer is equipped with a dial to control the angle of cross-polarization.
Digital Imaging
This microscope comes with an HDMI-capable digital camera, delivering 1080p video up to 60fps, and 2MP still images, even in low light. The highly sensitive digital sensor makes this camera ideal for low-light applications, including darkfield and fluorescence. Able to be used as a standalone recording device using Secure Digital memory, or as a wi-fi camera on a networked computer, this is an extremely flexible imaging solution.
Connected to an HDMI monitor or TV, 1080p live video can be viewed at a super-smooth 60fps. The included USB mouse allows you to make adjustments in the internal software for settings such as white balance and exposure, and control recording functions. As an alternative solution, connect to the camera over WiFi for remote software control, with 25fps streaming. The included Windows software offers image-development and measurement tools, as well as advanced compositing features such as image-stitching and extended depth of focus. With the ability to calibrate scales at multiple magnifications, the software can be used for multi-level inspection. For Mac and Linux, there is a lite version of the software that can capture video and still images and includes limited processing features.
