They are fast, vibration-free due to their small size, and they offer exceptional versatility. These outstanding features are characteristic for Leica Microsystems fast filter wheels for excitation, attenuation and emission control. Their short switchover times render them suitable even for highly complex applications such as FRET or CA++ imaging (Fura2).

Visible light at night (top) shows cities, gas flares, and moonlight reflected off clouds. Flares also shine in midwave infrared (lower); this view also contrasts warm waters with colder land and clouds. (NASA/NOAA image by Jesse Allen and Robert Simmon, using VIIRS data from NGDC.)

Infrared (IR) light—specifically between 6,000 to 7,000 nanometers—is critical for observing water vapor in the atmosphere. Though water vapor makes up just 1 to 4 percent of the atmosphere, it is an important greenhouse gas. It is also the basis for clouds and rainfall. Water vapor absorbs and re-emits energy in this range, so infrared satellite observations can be used to track water vapor. Such observations are integral to weather observations and forecasts.

Thermal or longwave infrared (TIR or LWIR) light includes wavelengths between 8,000 and 15,000 nanometers. Most of the energy in this part of the spectrum is emitted (not reflected) by the Earth as heat, so it can be observed both day and night. Thermal infrared radiation can be used to gauge water and land surface temperatures; this makes it particularly useful for geothermal mapping and detection of heat sources like active fires, gas flares, and power plants. Scientists also use TIR to monitor crops. Actively growing plants cool the air above them by releasing water through evapotranspiration, so TIR light helps scientists assess how much water the plants are using.

Microscopes for Industrial Applications from Leica Microsystems help you minimize downtime through a broad range of solutions and expert local support.

Midwave Infrared (MIR) ranges from 3,000 to 5,000 nanometers and is most often used to study emitted thermal radiation in the dark of night. Midwave infrared energy is also useful in measuring sea surface temperature, clouds, and fires. The images below contrast a visible-light nighttime view of the Niger River Delta with the same view in midwave infrared; both images are from the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi-NPP satellite. The day-night band shows visible light—the lights of Port Harcourt and Benin City, bright gas flares, and moonlight reflected off clouds. The midwave infrared image shows emitted thermal radiation. The warmer ocean and river are pale, while the cold land and clouds are dark, and the hot gas flares are bright.

Shortwave infrared (SWIR) light includes wavelengths between 1,100 and 3,000 nanometers. Water absorbs shortwave infrared light in three regions: 1,400, 1,900, and 2,400 nanometers. The more water there is, even in soil, the darker the image will appear at these wavelengths. This means SWIR measurements can help scientists estimate how much water is present in plants and soil. Shortwave-infrared bands are also useful for distinguishing between cloud types (water clouds versus ice clouds) and between clouds, snow, and ice, all of which appear white in visible light. Newly burned land reflects strongly in SWIR bands, making them valuable for mapping fire damage. Active fires, lava flows, and other extremely hot features “glow” in the shortwave-infrared part of the spectrum. In the image below, different types of sandstone and limestone make up the mountains around China’s Piqiang Fault. Each rock type reflects shortwave infrared light differently, making it possible to map out geology by comparing reflected SWIR light. Enhancing the subtle differences between the 3 bands of reflected shortwave infrared light used to make this image gives each mineral a distinctive, bright color.

Near infrared (NIR) light includes wavelengths between 700 and 1,100 nanometers. Water absorbs NIR, so these wavelengths are useful for discerning land-water boundaries that are not obvious in visible light. The below image shows the near infrared view of the Piqiang Fault, China. Stream beds and the wetland in the upper left corner are darker than the surrounding arid landscape because of their water content. (See a natural color view of the scene here.) Plants, on the other hand, reflect near infrared light strongly, and healthy plants reflect more than stressed plants. Finally, near infrared light can penetrate haze, so including this band can help discern the details in a smoky or hazy scene.

The graticule diameter is D = 26 mm. Specifications are engraved on the eyepiece, e.g. HC PLAN 10x/20 👓 M. HC PLAN = correction type, 10x = magnification/20 = field number FOV 👓, = for eyeglass wearers (high exit pupil), M = dioptric adjustment/graticule holder.

Hoya Softener .05 and the stronger Softener 1.0 are filters with randomly arranged drops of water on the surface of optical acrylic.

Staining and fluorescence techniques, like immunofluorescence or the use of fluorescent proteins, are used to make selected structures or proteins visible. Thus, to optimize the use of a microscope it is reasonable to learn more about its basic characteristics.

A wide range of eyepieces with 10x, 12.5x, 16x or 25x magnification (for field numbers of up to 25 mm) are available for the tubes. Special eyepieces for eyeglass wearers are available, as are eyepieces with adjustable eyelenses (M eyepieces) designed to accommodate a variety of graticules.

10x eyepieces are standard; eyepiece magnifications of 16x and 25x are intended for special applications only. All eyepieces have removable or fold-down eyecups and can be used with or without eyeglasses.

The precise setup of an optical microscope including correct Koehler illumination improves image quality – the base for further image analysis. Within light microscopy we differentiate between stained and unstained samples influencing the amplitude and the phase of the light waves traversing the sample. For the human eye, differences in the amplitude are visible as brightness differences.

Eyepieces identified with M are equipped with a focusing eyelens for dioptric equalization (from –6.8 to +4.2 or –6 to +5) and graticule holder. The external diameter of the eyepieces is D = 30 mm.
