When selecting a light source, it is important to choose a high-quality product by comparing offerings from different manufacturers. However, identifying a light source with reliable specifications that meet your needs can be challenging. The ideal choice depends on your evaluation criteria, as required specifications, accuracy, and performance vary by application. The following tips can help you quickly identify a light source that is both accurate and reliable. ① Select a light source with high uniformity and the appropriate brightness metric: Luminance or Illuminance. Uniformity of a light source is one of the most important factors to define the quality of itself. In terms of visual lights, luminance and illuminance are mainly used as photometric measures of the light intensity. Luminance describes the luminous intensity travelling from the light source in a given angle, while illuminance describes the light hitting ...

We developed LED artificial sunlight illumination under the trademark "eclat". Our LED has a broad spectral power distribution which is similar to the sunlight spectral power distribution (Please refer to images below). We use violet excitation LED which rise spectral wavelength from around 380nm to around 780nm. In addition to this, we can customize spectrum for your your requirements by adding other wavelengths from UV (Ultra Violet), visible lighting spectrum (VLS) to near infrared (NIR) range, for example, 365, 860, 940, 950, 960, 1060, 1300, 1450, 1550 [nm]. You can use it in the agriculture industry for indoor planting and seeding purpose, in automotive industry for interior and exterior color and scratch evaluation, in art industry for art painting evaluation, etc.  Additionally, it can reproduce lighting for your evaluation under different weather conditions as well, and the evaluation can be ...

We developed a new fiber optic light source equipped with two high power intensity LED; 1300nm/ 1550nm. Comparing with Halogen, an intensity of 1300nm is twice as halogen, on the other hand, an intensity of 1550nm is  three-quarters (3/4) as Halogen. In addition to this, feedback function for brightness stability is added to fiber optic light sources. If you have an interest in it, please feel free to consult us. Contact us from here ...

We developed a demo unit of a new illumination box for the visual inspection. This is designed for the color inspection, the flaw detection. Maximum intensity is 35,000lx. If you are interested in this, please consult us at first. ・This is the illumination box with artificial sunlight illumination SOL series as  a light source ・Width 97cm box makes it possible to test a large object ・Equipped with four illumination boxes using high color rendering LED: Ra-97 ・Illumination b0oxers are detachable, therefore it can add an extra illumination  box, change to other spec illumination boxes by a test purpose. ・Four illumination boxes can be controlled individually or totally by operational part ...

We usually use gray charts or pattern charts to evaluate Dynamic range of image sensors, however this solution is not perfect for features of charts and light sources. Even though charts have sophisticated patterns, dedicated colors on itself, it should be lighten by light source such as a surface LED light box, which means patterns on a chart are effected one  another by transmitting lights from the light sources. Also even though light sources have strong enough to irradiate stable lights to a transparent chart. Therefore we cannot say that using charts is completely accurate evaluation for DR and relative factors. LSB-0303HDR-2415 was developed by considering about this problem. This light source box has 24 cells of different brightness lights, which can be controlled individually to change each cell's brightness. In addition to this, each cells are surrounded by matted ...
