ZOOM LENS WHICH IS GOOD IN NEAR RANGE FOCUSING FUNCTIONPURPOSE:To obtain the variable focus lens which is wide in its picturing angle at its short range focusing, by setting up the focus distance on the primary and secondary auxiliary lens group to a specific relation.TANAKA KAZUO...
In the variable focus lens of the monitoring camera is configured to stop (S) disposed between said third lens (L3) and the fourth lens (L4), the refractive index and the dispersion coefficient of the first to tenth lens with a predetermined value By improving the configuration, lens MTF va...
20. The near-eye display system of claim 19, wherein the plurality of image portions at a plurality of focal lengths are created based on one or more of: per pixel adjustment of the light path length, time sequential adjustment of the light path length, and variable adjustment of the ligh...
A DLP with a “birdbath” would typically use the non-polarizing beam splitter with a design similar to the ODG R-9 but replacing the OLED microdisplay with a DLP and illumination. As an example, Magic Leap did this with a DLP but adding a variable focus lens to support focus planes....

and a shortwave infrared (SWIR) fixed focus lens (HS2514V-SW; Myutron Inc.). To eliminate the visible light waves, we used a long-pass filter with a cutoff wavelength of 900 nm (FELH0900; Thorlabs Inc.). As the LCRs, we used two liquid crystal variable retarders with an aperture ...
the cut-off wavelengths are from 1150 nm (1.07 eV) to 1470 nm (0.84 eV) (Fig.4g, h). Interestingly, the experimentally measured bandgaps reduce 0.23 eV, which is in good agreement with our theoretical prediction (0.27 eV, Fig.2). The variable spectral photoresponse ra...
Here, we propose a microfluidic paper-based analytical device (µPAD) implemented with a near-field communication (NFC) tag as a portable, simple and fast colorimetric method for glutathione (GSH) determination. The proposed method was based on the fac
In addition, the emission near supermassive black holes is highly variable, with bright high-energy flares regularly observed. We demonstrate that intrinsic variability can introduce prominent associated changes in the relative brightness of the photon ring. We analyze both semianalytic toy models and ...
