"I don't have time to send it in for calibration." "Calibration cost is expensive." "I want to use the same standard for multiple luminance meters." Introducing a reference light source with stable brightness and high reproducibility is an effective solution to these issues. Tsubosaka Electric offers industrial diffused surface light sources that ensure high uniformity over 95% in brightness, color temperature, and stable luminance values all-times. High Uniformity Ra over 95 Reproduce any color temperature Stable luminance We offer light sources for calibration that are ideal for assisting with luminance meter calibration and differential management. A stable reference light source ensures reliable daily inspections and differential management of multiple luminance meters. Our lineup includes brightness settings ranging from a single fixed point to an adjustable type that can reproduce any luminance value by using a numeric keypad. You can choose the ...

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 ...
