Abstract
In order to overcome the deficiency in safety performance of a lens (made of glass) used in the current single-chip LCD projector, the utility model provides a game type education projector lens, which is characterized by arranging a piece of optical glass lens between the two pieces of plastic lenses, thereby solving the problems of safety performance, reducing the manufacturing cost greatly, and being particularly suitable for the game type education projector lens used by children. The focal length f of the game type education projector lens is equal to 100mm, the F/# is 2.7, and the image throw ratio is 2.1.
Description
Technical field
The utility model relates to Single panel LCD (abbreviation of Liquid Crystal Display) projector projection objective (hereinafter to be referred as camera lens), is applied to the imaging field of transmissive liquid crystal display technology, is specially adapted to the imaging lens of game type education projector.
Background technology
The projection lens that Single panel LCD projector adopts at present generally adopts the optical glass of three to five unlike materials to be made, and is dangerous because of Glass breadks easily, and for the game type education projector that children use, its security performance is particularly important especially.The utility model adopts two PMMA material (plastic cement acrylic) eyeglasses and a slice optical glass lens group to close and forms, and a slice optical glass lens is between two plastic lens, solved security performance, and also greatly reduction of manufacturing cost, it all is the camera lens of optical glass lens that resolving power can reach.
Summary of the invention
Deficiency (being made by glass) for the security performance that overcomes present Single panel LCD camera lens that projector uses, the utility model provides a kind of and closes the Single panel LCD projector lens that forms by two PMMA materials (plastic cement acrylic) eyeglass and a slice optical glass lens group, wherein a slice optical glass lens is between two plastic lens, the utility model focal distance f=100mm, F/# are 2.7.
The utility model is comprised of three eyeglasses, and by L1-L3 shown in Figure 1, L1, L3 are plastic lens, and L2 is optical glass lens, each eyeglass has two spherical radius, has 6 faces, and its spherical radius respectively is from left to right: 32.44,1233,48.66,35,122.65,38.11mm; The L1-L3 bore respectively is: 33.55,26.55,30.78mm; Its center thickness respectively is: 5.83,0.65,5.15mm; Airspace between the eyeglass is followed successively by: 11.37,11.41mm.The effective total length of camera lens that forms is 34.41mm.
Three eyeglasses are separated according to the airspace required distance between them by the eyeglass spacer ring and form integral body, i.e. a utility model.Be the eyeglass spacer ring by G1 shown in Figure 1, G2.
The utility model needs the liquid crystal board with a slice LCD in use, as the object plane of projection lens, is placed in the right of the present utility model, through camera lens (the utility model) imaging, is imaged on the left side of the present utility model, and the picture projection is than 2.1.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural drawing of the present utility model.Require three eyeglasses to be separated and form integral body, i.e. a utility model by two eyeglass spacer rings according to the airspace between three eyeglasses.L1-L3 is three eyeglasses, and L1, L3 are plastic lens, and L2 is optical glass lens, and namely a slice optical glass lens is between two plastic lens.G1, G2 are the eyeglass spacer ring.
Embodiment
The utility model is closed by two plastic lens and a slice optical glass lens group and forms, plastic lens is made mould according to spherical radius, center thickness and bore requirement, and is injection molded, glass mirror is according to spherical radius, center thickness and bore requirement, and grinding forms.Three eyeglasses require three eyeglasses to be separated and form integral body, i.e. a utility model by two eyeglass spacer rings according to the airspace between three eyeglasses.
The utility model in use, need the liquid crystal board with a slice LCD, object plane as projection lens, be placed in the right of the present utility model, through camera lens (the utility model) imaging, be imaged on the left side of the present utility model, the picture projection is than 2.1, be projector distance 870mm, 20 inches of picture catercorner lengths.
