process of cleaning the optical drive. The bald lens is usually located next to the spindle motor and is a light blue mung bean-sized thing. This blue laser head lens is fixed on the elastic object, note that the wipe should not force too much, otherwise it will make the bald-headed offset.

Projector is a precision electronic products, it sets machinery, liquid crystal or DMD, electronic circuit technology in one, the use of the process is the projector is more delicate, often careless will appear a variety of accidents. That said, but if used properly in daily use, plus the usual little maintenance, the projector will not be so prone to failure problems. Below we will use the projector from the projector and the daily maintenance of the two points to a simple talk about how to mai

rotated along the optical Center (or node) of the lens. The node of the lens is a point where the light path converges in the lens before focusing on the camera sensor or film plane. Rotating the camera in the center of a tripod socket will almost certainly result in parallax errors, so you need to locate the node first, then fix the camera, and then rotate the

D80 faq q 1. Manual lens usage for D80 D80 can use a manual lens with a Nikon F bayonet, such as Zeiss's ZF lens, but it can only use the M file! Because D80 does not support the input of non-CPU lens data, cosina made two new freunda lens 58f1. 4 and 40f2 because the

Aperture factor: The aperture factor is the value of the lens focal length divided by the diameter of the optical hole, expressed in F For example, there is a third lens: a lens with a focal length of 50mm, the maximum aperture diameter of 25mm, then the aperture coefficient is 50/25=2, we say it is F2 lens; The

35. Draw the lens. Select the fuselage layer, press Ctrl+r to open the ruler, select the Move tool, and in the upper-left corner of the window, check the "Show bounding box" so that you can easily pull the horizontal guide line from the midpoint of the fuselage.

In the process of learning Unity , the most basic and most important part is the lens control . Lens control is through the mouse, keyboard and other input device operation, to achieve in-game navigation. The essence of Unity is to transform the position (position) and rotation (rotation)of the camera object by receiving the mouse's movement and keyboard keys, These two values are located in the camera's t
