Caption: Figure 4: Relationship between the PTC focal distance and cavity open length under different concentration ratios and tracking error angles.
The distance between the source and the lens is [d.sub.1], the LHM lens length is [d.sub.M], and the focal distance is f.
Therein, F denotes the focal distance, N represents the refractive index of material, [R.sub.1] is the radius of front curvature, and [R.sub.2] is the radius of rear curvature.
A previous calibration in air and in a test tank provided correlation rules between raw data and field angle or focal distance.
The Omnivue medical magnification task light offers an extra-large, fully pivoting, 6.5-inch by 4.25-inch 3D lens which provides 1.75X magnification power and a focal distance of 13.3 inches.
The relations for the attenuation of velocity and acceleration amplitudes are expressed in terms of magnitude, focal distance and generally in seismic transmission functions of the station subsoil.
Scripter Liu s wry tone, incorporating a "Psycho"-type switch of protagonists midstream, is well served by helmer Liu's compelling, static compositions, and story's strange perspective seems at one with the camera's startling changes of angle and focal distance. Pic deservedly copped top honors for feature and director at Tribeca, and it shouldn't be long before some enterprising distrib throws this distinctive "Hat" in the arthouse ring.
Several temperature models between 250-3000 C are available with target size ranges between 0.040"-2.300" diameter at focal distance from 4"-120".
Although there is usually sufficient latitude, focused grids also experience grid cut off if the grid is not positioned at the intended focal distance.
Several temperature models between 259[degrees]C and 2,981[degrees]C are available with target size ranges between 1 mm and 58 mm diameter at a focal distance of 101 mm to 3,048 mm.
These lenses provide a high index for applications where closer focal distance is required.
Through-the-lens sighting ensures simple 'point and click' operation, with the unit's single lens reflex optics and a circular reticule in the viewfinder displaying the exact target area measured at the fixed focal distance of 4 metres.
