In the field of optical testing equipment, the genuine evaluations from customers are the most powerful proof of product quality. From the R&D workshops of photovoltaic enterprises to the laboratories of aerospace institutions, from the planting greenhouses of agricultural bases to the inspection lines of automobile factories, the LED solar simulators of Saifan Optoelectronics have won unanimous recognition from customers in various industries with their outstanding performance. These voices from front-line users jointly outline the hardcore strength of Saifan equipment as a benchmark for optical testing.
Photovoltaic research and development: "Stable data enables scientific research to avoid two years of detours
In the past, when testing perovskite batteries with traditional equipment, the data deviation under the same conditions could reach 2%, and it would take half a year to reach a reliable conclusion. After switching to the Saifan simulator, the spectral matching accuracy was controlled within ±0.5%, and the special response of the material in the 780nm band was captured within three months. Professor Li, the director of the photovoltaic materials laboratory at a certain university, expressed the feelings of many researchers. It is precisely because of this precision that the team successfully increased the battery conversion efficiency by 3 percentage points, and the related results were published in an authoritative journal two years ahead of schedule.
During the mass production inspection stage, Wang, the quality inspection director of A leading photovoltaic enterprise, also gave a high evaluation: "Our production line inspects tens of thousands of solar cells every day. The speed of 60 cells per minute and the testing accuracy of ±0.3% of the Saifan equipment have increased the A-grade product rate from 88% to 93%, reducing the loss of defective products by over ten million yuan annually." What's more important is the stability of the data. There's no need to worry about the problem of "qualified in the morning but exceeding the standard in the afternoon" anymore.
Aerospace testing: "Space-level reliability makes us feel at ease entrusting the mission to him."
It is well known that the aerospace field has strict requirements for equipment. Engineer Zhang from the Beijing Institute of Aerospace Metrology and Testing Technology frankly stated, "In the material testing of spacecraft, we have tried the equipment of three manufacturers. Only Sivan could stably output the AM0 spectrum continuously for 720 hours at a low temperature of -40 ℃, with the light intensity fluctuation not exceeding ±1.2%." It is precisely this stability that has helped them screen out high-performance protective materials for the Chang 'e lunar exploration project, extending the lifespan of the spacecraft's coating by three times.
The testing team from the China Academy of Space Technology was deeply impressed by the customized service: "To simulate the surface lighting environment of Mars, we proposed a special requirement of 'AM0 spectrum + infrared enhancement', and the engineers from Saifan completed the transformation in just 10 days." Now this set of equipment has become the core device for the power supply system test of the Mars rover, and the data match the actual measurement in orbit by 99.2%.
Agricultural planting: "Spectral formula increases the value of agricultural products by 30%
Ms. Chen, the technical director of the high-end flower base in Yunnan, shared her surprise: "We used the plateau ultraviolet spectrum customized by the Saifan simulator to cultivate blue roses. The anthocyanin content in the petals increased by 22%, the flowering period was extended by 7 days, and the market premium reached 30%." This "light formula" has now become our core competitiveness, and our peers are all inquiring about the source of the equipment.
Wang, the director of the Shandong Strawberry Planting Cooperative, did the economic calculation: "Through the red and blue light ratio scheme designed by the Saifan team, the sweetness of strawberries has increased by 2 degrees, the yield per mu has increased by 150 kilograms, and the maturity period has also been advanced by 10 days." At the current market price, each mu can earn an additional 5,000 yuan, and a 20-mu base can increase income by 100,000 yuan in a year.
Automobile Inspection: "Extreme Scenario Testing Makes autonomous Driving Safer"
In the field of intelligent vehicle research and development, Liu, the sensor testing director of a certain new energy vehicle company, highly praised the scene simulation capabilities of the equipment: "The 20 extreme light scene libraries constructed by the Saifan simulator are extremely practical." We found that the sensor had a 50-millisecond delay in the tunnel glare scene, and after optimization, it was shortened to 10 milliseconds. Now this set of testing standards has become an industry reference, and this is inseparable from the precise data support of Saifan equipment."
The material testing laboratory of this enterprise also benefited: "When testing on-board photovoltaic glass, the equipment simulated the light characteristics of different regions, helping us optimize the best light transmittance design and increase the on-board power generation by 18%." This ability to "customize lighting according to demand" is much more efficient than traditional equipment.
Service guarantee: "2-hour response reduces production halt losses to zero."
When it comes to after-sales service, Mr. Zhao, the equipment supervisor of a certain auto parts enterprise, has a deep understanding: "Once, the inspection line suddenly broke down. We contacted the customer service of Saifan at 3 a.m. The engineer arrived at the scene in two hours and completed the repair in four hours, avoiding an average daily production halt loss of 500,000 yuan." The rapid response from the seven spare parts centers across the country has made us feel particularly at ease when using them.
Today, Saifan Optoelectronics' LED solar simulators have served over 200 customers worldwide. The repurchase rate of core customers is as high as 82%, and 85% of new customers come from referrals by existing customers. From scientific research breakthroughs to industrial upgrading, from cost savings to value creation, these genuine evaluations from various industries jointly confirm the quality and strength of Saifan Equipment. As a certain aerospace client commented: "Choosing Saifan means choosing a light testing solution that allows data to speak and word-of-mouth to bear witness."
