Understanding Oblique Single-Plane Illumination Microscopy (oSPIM)
 
By Dan Croucher, Photometrics

Oblique Single Plane Illumination Microscopy (oSPIM) is a platform for high-resolution light sheet microscopy that combines the low photo-bleaching and photo-damage of LSFM with high magnification, high NA objectives for cellular and subcellular imaging. This paper describes how oSPIM works, its advantages over conventional fluorescence microscopy, and the equipment required for this technique.

Interference Microscopy For Surface Structure Analysis
By Peter J. de Groot, Zygo

Utilizing interference microscopy techniques to measure the many aspects of surface structures takes advantage of rapid, noncontact operation and rapid data acquisition, often at data acquisition rates in the millions of 3D image points per second. 

Microscope For Fluorescence Microscopy

Mad City Labs’ RM21 microscope is a microscopy platform designed to allow direct access to the entire optical pathway and is capable of precision alignment in the X, Y, and Z axes. The Z-axis objective lens holder is aligned with the platform's optical axis and can hold a single objective lens. 

ColdVision Series For Machine Vision And Microscopy Illumination

The ColdVision series from SCHOTT Lighting and Imaging is composed of an extensive array of light sources, fiber optic guides, and accessories designed to work seamlessly with each other for illumination purposes in machine vision and microscopy applications. 

Automation And Microscopy: Faster Test And Measurement

Nanotechnology uses the concept that constant velocity will get you to the destination faster than constantly stopped traffic. One technique puts this concept into practice via a fast nano-focus device based on a piezo-ceramic actuator embedded in a flexure guided lens positioning mechanism.

Compact sCMOS Camera

The new pco.panda is a sCMOS sensor camera system designed to provide high quantum efficiency with the lowest dark noise for applications including single molecule detection, bio- and chemiluminescence, GSDIM, PALM, STORM, SPIM, and more. It also is housed in a compact, 65 x 65 x 65 mm3 package.

Digital Encoder Galvano Scanner: GM-1000 Series

The GM-1000 series of digital encoder galvano scanners comprises four different models with variations in beam diameter, scan angles, small step response, and resolution. Each model has a compact physical profile, super low thermal drift, and extreme high resolution, precision, and accuracy.

Shortwave Infrared Adaptive Optics And Applications
By Raf Vandersmissen, Xenics

This article introduces adaptive optics and the benefits of using (shortwave) infrared cameras in wavefront sensing for applications including astronomy, laser communication, biological imaging microcopy, and retinal imaging in combination with optical coherence tomography.

Theory And Measurement Of The Modulation Transfer Function (MTF)
By Image Science

MTF is a quantitative and objective measure of the quality of an image formed by a lens or an electro-optical system. This measurement is appropriate for lenses of all qualities and can be calculated from lens design data, which enables theoretical and actual performances to be compared. 

How To Assess Thermal Camera Range For Site Design
By John Love, Leonardo DRS

When laying out a site design for surveillance using currently marketed uncooled thermal cameras, it is important to understand the coverage capability of the cameras under evaluation in terms of field of view and range.

You Cannot Manage What You Cannot Measure: Optical Filter Manufacturing
 

On the first day of DCS 2017, Jason Palidwar, with Iridian Spectral Technologies, spent a few minutes with us talking about the three key criteria that apply to all of the filters his company manufactures – surface quality, spectral characteristics, and durability and reliability.

LIDAR Guns, Accuracy, And Speeding Tickets
 

A light detection and ranging (LIDAR) system uses a 130 μW 904 nm beam, produced by three light emitting diodes (LEDs), and a telescope working together in order to calculate how long it takes for the beam to leave the device and return to the telescope.
