Description
Technical field
The utility model relates to mechanical field, particularly a kind of solar simulator.
Background technology
The subtended angle of sun light-emitting area to point arbitrary on the earth is called angle of collimation.The earth runs on near-circular orbit around the sun, is 32'36 at perigee subtended angle ", apogee subtended angle is 31'31 ", therefore in small-sized solar simulator, sunshine angle of collimation is taken as 32' ± 0.5' usually.

But, optical integrator is used can to run into following problem in so small-sized solar simulator:
1, for reducing system bulk, the focal distance f of collimating mirror ' can not get very large (usually at about 1000mm, getting 1000mm is here example), then the radius of diaphragm is 1000 × tan (32'/2) ≈ 4.65mm, and size is less.Integrator is close to diaphragm, effective aperture and aperture stop size close, therefore each lens dimension of optical integrator needs very little, the processing of eyeglass and install fixing more difficult.
2, making optical integrator at present utilizes transparent optical cement that the eyeglass arranged is bonded on a slice parallel mat often.Like this, when requiring the illumination height exported, the temperature near optical integrator will be very high, and optical cement cannot meet high temperature resistant requirement.
Increasing and the existence of seam 3, due to optical element, will reduce the efficiency of system, increase the difficulty of heat radiation.
4, export the adjustable situation of illumination for solar simulator, if use optical integrator in system, when exporting illumination and being lower, the seam between optical integrator eyeglass will appear on face to be illuminated significantly.
As shown in Figure 2, condenser 2 is an ellipsoid, for installing light source 1, condenser 2 has a bottom outlet, and the light causing condenser 2 to converge has a brightness breach, after collimator objective 5 collimates, there is a circle blackening at face to be illuminated 6 center, cannot meet the requirement of solar simulator to homogeneity.
