variable of a zoom operation member exceeds the moving speed of the power varying lens in fixed-speed zooming operation wherein the current moving speed of the power varying lens is held with a specific switch, such as a seesaw switch, is turned on in the operation of the zoom operation ...
The magnifying power of the objectives alone usually ranges from 4x to 100x, and the power of the ocular alone ranges from 10x to 20x. The total power of magnification of the final image formed by the combined lenses is a product of the separate powers of the two lenses: Microscopes are ...
英语翻译BARRON上的一段话,没看明白As with a single slit,the light going through a lens is diffracted.The amount of diffraction is usually negligible,but one effect is that parallellight entering the lens is brought,not to a point focus,but to a disk focus
(that is, Δz = 1.2 µm across a 400-µm FOV). The long path length inside the immersion medium means that the image quality depends on the homogeneity of the liquid. As a consequence, we could not achieve satisfactory image quality in CLARITY samples because the required ...
The glass surface inside the tube is also sealed from the atmosphere protecting it from dust and other lens disturbances, reducing the need to clean the lens. High-quality refractors can also provide crisp, high-contrast images with high magnification, making refractors a great telescope for astr...
Check Price on OpticsPlanet This is Vortex’s response to many of the top-tier riflescopes suitable for shooting at long ranges. It features magnification settings between 5 and 25x and has a 50 mm objective lens. The reticle is set on the second focal plane, so it’ll remain the same...
On the other hand, Raman can be insensitive to asymmetric stretches to which infrared spectroscopy is sensitive. The power of Raman spectroscopy originates from the fact that the activity of Raman modes depends both on the form of a vibrational harmonic and the stereochemistry of the molecule in...
A zoom magnification is calculated based on a focal length of a photographing lens obtained before zooming and the focal length of the photographing lens o... 勝俣 百恵 被引量: 0发表: 2014年 In the photographing glass lens which consists of with the 1st glass lens PROBLEM TO BE SOLVED: ...
position that is reached when the SYNC signal from the laser (i.e., the STOP signal) is received. The downside of the TDL approach is that the maximum delay measurable (i.e., the temporal range) depends on the length of the TDL, and thus on the available FPGA-resources. To keep ...
Geneticist Mae-Wan Ho captures this idea with her portrayal of life as “quantum jazz,” describing it as “an incredible hive of activity at every level of magnification in the organism . . . locally appearing as though completely chaotic, and yet perfectly coordinated as a whole.” Life ...
