Laser light is concentrated on a specimen either as a point source for microscopic work, as a divergent light cone for smaller-sized specimens (with the aid of a laser diffuser), or a collimated beam (in which all light rays are parallel) is raster scanned over very large specimens. Since the laser is very bright, it must be blocked with an appropriate filter that still allows the longer wave fluorescence signal to pass through. Proper precautions using laser-blocking protective glasses and manufacturer’s safety protocol should be followed.
The equipment used with this methodology depends on the exact wavelength of light produced by the laser. Specialized light-blocking longpass filters, often used in astronomy, are best-suited for these methods. These particular filters will allow all wavelengths of light longer than a certain wavelength to pass through the filter, however, it will stop all shorter wavelengths. For instance, a red-orange longpass filter (LP580, MidOpt) will allow 91–95% of light between the wavelengths of 600–1100 nm, however, the transmission sharply decreases between 600–520 nm, and by 510 nm, no light passes through the filter (
Standard UV bulbs can be used in addition to lasers in order to cover a broad range of the light spectrum. Imaging is done in both UVA from 315–400 nm and UVB from 280–315 nm. When working with UV light, photographs can be taken both with and without filters due to the low UV sensitivity of digital camera CCD (charge-coupled device) chips.
No special digital cameras are needed to photograph specimens using laser fluorescence. Typically, digital single lens reflex cameras (DSLRs) capable of manual time exposures (e.g. Nikon D610) with either wide angle or macro lenses are sufficient. Ideally, the photography should be done in a darkroom, basement, or office without windows or with blackout curtains, as any influence of natural light will reduce the clarity of the fluorescence. The use of a tripod is necessary, as the exposure time during photography is typically long—up to several minutes, although this may not be the case for close macro photography. The aperture setting (f-value) should be as low as possible for long-exposure shots.
Multiple types of laser light sources can be used. The more powerful the laser, the better and brighter the fluorescence. For the experiments outlined here, class III lasers in the 300–500 mW category were used. These were well below the threshold that results in radiation damage to the specimens studied. A lab laser, which plugs into the wall and is fairly static, and a high-powered laser pointer that runs off of CR123A lithium batteries, have both been used successfully depending on the locality of the specimen. The benefit of using a lab laser is that it can be used for hours at a time without overheating. It is typically used for precision work and photographing larger specimens. A high-power laser pointer is more portable and adjustable than a lab laser, however it can only be used for ~5 minutes, or else it will overheat and become damaged. If the photographer knows what f-value and shutter speeds are necessary for photography, a laser pointer can be used to great effect. It is excellent for macro photography in the field due to its portability.
A laboratory setup for table-top-sized specimens would typically hold the laser on a fixed mount (
Larger specimens can be scanned using a custom device (
For a microscope setup, the collimated laser beam is directed through one of the illumination ports or projected directly onto the specimen. The emitted light, laser and fluorescence, comes back through the microscope’s optical train where a longpass filter is placed either before the objective lens or internally in a filter slot to block the intense laser light. The fluorescence can then be observed and photographed in detail.

Example 3
Coatings were deposited onto each of Pebax rods (72D; 63D; and 35D—40% BASO4), NYLON-12 rods, PEEK rods, and HDPE rods.
Specifically, coating solution A was applied to each substrate using a dip coat method. Specifically, the substrate was immersed in the base coat coating solution with a dwell time of 5 seconds. The substrate was then extracted from the solution at a speed of 0.3 cm/s. The first layer was then air dried for at least 10 minutes. The first layer was then UV cured. Specifically the coated substrate was rotated in front of a Dymax 2000-EC series UV flood lamp with a 400 Watt metal halide bulb for 3 minutes, approximately 20 cm from the light source.
Next, coating solution B was applied to the first layer, also by dip coating at the same speed to form the second layer. The second layer was then air dried and UV cured using the same conditions as for the first layer.
The friction of the coating on each substrate was then tested according to the testing procedure outlined above. The results are shown in
