Palm big vision Optoma SL1 portable entertainment micro-invest evaluation
In recent years, smart micro-projection has been favored by users with its compact size and flexible delivery mode, especially since it has been received by young users. As a veteran projector manufacturer, Optoma has launched a mini-projector product in 2008. At that time, the product received widespread attention from the industry and was extremely popular. In February of this year, after reviewing market experience and in-depth analysis of user needs, Optoma launched its own new micro investment SL1. Today, let us experience how this new product will bring a new experience.

Optoma SL1 performance measurement Our test of the projector mainly through the brightness measurement, work heat and body weight and other angles to test, due to the different use of the environment, users should consider their own playback environment, and external light effects and other factors Our test will also minimize the error and provide you with objective data for reference only.
♦ Spectrophotometer We measure the actual brightness and contrast of the projector product through a spectrophotometer. The photometric method determines the substance by measuring the absorbance of the measured substance at a specific wavelength or within a certain wavelength range. Quantitative analysis. The commonly used wavelength ranges are: (1) an ultraviolet region of 200 to 400 nm (2) a visible region of 400 to 760 nm, and (3) an infrared region of 2.5 to 25 μm (in terms of wave number, 4000 to 400 cm).


♦ Electronic weighing We will objectively weigh the product during the test. Weighing takes the total weight of the body and the necessary wire, making the weight reference for the user when carrying the projection device.
♦ Temperature measurement**
Using the principle of infrared temperature measurement, the radiant energy emitted by the infrared rays emitted by the object is converted into an electrical signal. The size of the infrared radiant energy corresponds to the temperature of the object itself. According to the size of the electrical signal, the temperature of the object can be determined.
♦ Test result

Optoma SL1 high-definition sample test We take a look at the effect of the product in practical applications in the final comparison, the most useful use of home projectors is the video playback, while the HD movie playback is also very test the product details and color performance ability. In the following tests, we all selected high-definition pictures for fixed scene shots.









Optoma SL1 document picture and focus ability test document picture test can accurately and effectively reflect the projector's product in the details of the quality and text performance, while the product's focus ability can be detected.



In fact, in most people's minds, Optoma is an established projector manufacturer with obvious advantages in the home market and engineering market. Like the recently launched 4K home projector series, outstanding color performance, excellent product performance is very eye-catching, has become the home market explosion. In the micro-projection block, everyone thinks that Optoma is a new recruit. Actually, Optoma has launched micro-projection as early as 08, and has foreshadowed it. The launch of the Optoma SL1 compact size, powerful performance, flexible applications, user-friendly details are all proclaiming the profound knowledge of Optoma.
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, etc. on TV boxes, smart TVs, smart TV software, etc. Answering questions.
The PLC splitter is used to separate or combine optical signals. A PLC is a micro-optical component based on planar lightwave circuit technology and provides a low-غير مجاز مي باشدt light distribution solution with the small form factor and high reliability.
Rackmount Splitter is manufactured using silica glass waveguide circuits that are aligned with a v-groove fiber array chip that uses ribbon fiber. Once everything is aligned and bonded, it is then packaged inside a miniature housing. PLC splitter has high-quality performance, such as low insertion loss, low PDL, high return loss, etc.
Advantages
Suitable for multiple operating wavelengths (1260nm – 1650nm); unstinted.
Equal splitter ratios for all branches.
Compact configuration; smaller size; small occupation space.
Good stability across all ratios.
High quality; low failure rate.
