07.25.22 -- How Acousto-Optical Tunable Filters Enhance Confocal Microscopy

Spotlight On Microscopy
Optical Filters For Raman Analysis: Finding The Needle In The Haystack

Most Raman microscopy applications seek to maximize access to the Raman fingerprint of the molecule of interest, requiring filters that provide “more signal with less background.” This article discusses optical filters for Raman analysis, addressing filters for both bench-top and portable Raman applications.

Utilizing Fluorescence Filters For Microscopy And Imaging

Because image quality is highly dependent on the design and overall performance of the fluorescence filters integrated into microscope and imaging systems, optical filter performance is just as important to the final image as sample preparation and fluorophore selection.

Acousto-Optical Tunable Filters Enhance Versatility Of Confocal Microscopy

AOTFs deliver sharper images, pixel-by-pixel wavelength flexibility, and precise control for confocal microscopy. Lars Sandström, vice president, life sciences at G&H, explores how the technology is evolving to further enhance the versatility of confocal microscopy in life sciences.

Objective NanoFocusing Stage Provides 800 µm Travel

The P-725 piezo nanopositioning scanner is for autofocus and metrology applications. PI’s piezo lens focusing stages have been improved with longer travel ranges to 800 µm, faster step/settle, and higher resolution.

Video: IR Microscopy – How To Get Accurate Temperature Measurements And Find Hot Spots Using The Proper IR Camera Lenses

Finding and fixing hot spots within ever-shrinking electronic systems has become more and more difficult. This webinar examines close-up and microscope lenses and how they allow infrared cameras to make accurate temperature measurements on components less than 25 µm in size and image targets as small as 3.5 µm. Side-by-side comparisons of real-world images are presented along with data from a variety of different camera and lens combinations.
