Reflectivity: 97-99% (visible light)
Whiteboard is the abbreviation of standard whiteboard and reference whiteboard. It is an optical transmission standard. It is a calibrated whiteboard with spectral reflectance data provided by the National Institute of Metrology (National Bureau of standards). Users should measure the optical properties of other samples according to this data. No matter what kind of instrument you use or what method you use, all measurement data should be traced back to the standards of the National Institute of metrology. Only in this way can the measurements of various countries be comparable, effective, accurate and reliable.
Basic performance of whiteboard:
1. Standard whiteboard is made of high-quality PTFE resin pressed, sprayed or foamed. It has good strength and can be washed with water;
2. The size of the standard whiteboard is Φ 30-100mm, or 30x30100x100mm, the larger is the target;
3. The reflectance data of the whiteboard is tested by China Institute of Metrology and transmitted as the standard value; Use wavelength 250-2500nm;
4. The reflection surface of the whiteboard is an ideal Lambert diffusion surface. The reflected light in any direction obeys the cosine law;
5. Whiteboard is mainly used for optical calibration and measurement, such as light source, color, spectral analysis, etc;
6. The white board has good optical stability, never deteriorates, and is not afraid of acid, alkali and salt corrosion;
In addition, we also make gray plates with reflectivity of 30% and 60%.
The target is essentially a large whiteboard with a size of 1 × 1 ㎡ or larger, which is a large-scale test dedicated to the field. For example, aerial remote sensing test and aerial laser guidance test
Some large targets are needed for simulation tests, such as experiments, even Aerospace experiments. Due to the good diffuse reflection characteristics of the target, the incident and receiving angles in a large range
Therefore, large test targets are necessary. The base of the target is generally cloth base, which is light and easy to use. High quality surface spraying
PTFE coating has high reflectivity, good diffusion characteristics, no fear of moisture and good strength. This target is mostly used for testing in China.
The basic performance of the target is the same as that of the whiteboard, but the size is different.
Target: size 1 × 1㎡

Standard Solar Cell
Standard Solar Cell
hgssc series standard solar cells are usually used for daily calibration or test of the total irradiance (w / M) established by the light source (xenon lamp, solar simulator, etc.) on the surface of the tested solar cell ²)。 When the irradiance of the solar simulator changes, the ratio of the short-circuit current irradiated on the solar cell to the irradiance of the solar simulator is close to a constant, so the solar irradiance can be obtained by measuring the short-circuit current. The calibration value of solar cell is defined as the ratio of short-circuit output current and irradiance of standard solar cell under standard test conditions, in a / (w / M) ²), Called CV value. When the short-circuit current of the solar cell is equal to its calibration value, it can be considered that the irradiance of the solar simulator reaches a solar constant, i.e. 1000W / m ²。
Air cushion shock absorber
Air cushion shock absorber
Product instructions:
This product is generally used in a group of 4, and each shock absorber is charged and deflated separately.
Install the four shock absorbers on the customer's support through the through holes at the bottom or other ways, and distribute them at the four corners as a whole.
The heavy objects to be damped shall be stably lifted and placed on it. The heavy objects shall be in good contact with the main bearing surface of each shock absorber and the ejector rod for venting, and the pressure gauge and inflation port shall face outward.
After unscrewing the inflation nozzle cap, each shock absorber can be inflated separately with domestic manual air pump, vehicle mounted inflation pump and other air sources. The inflation pressure range and airbag safety rise range are shown in the table above.
Height adjustment: when the four shock absorbers are used together, raise the floating height of the shock absorber by pumping air or releasing the gas of the diagonal or opposite shock absorber; Reduce the floating height of the shock absorber by deflating or inflating the diagonal or opposite shock absorber; (remember not to inflate and deflate a lot before making clear the rules. You can try a little inflate and deflate first). Manually lift up the ejector rod for venting. This air cushion shock absorber is similar when used alone.
Note: it is forbidden to expose this product to the sun, touch the airbag with sharp objects and avoid being contaminated with oil.
