Ambient Light Sensors

Excelitas Technologies is a leading provider of advanced photonic solutions that continuously meet the ever-changing demands of our customers. Our focus has always been to help our customers meet their optical, optronic, illumination, sensing, detection, and imaging needs. Our production of Ambient Light Sensors is a product of this commitment, which allows us to provide easy solutions for our customers and enable them to achieve the right products for suitable applications.

Excelitas provides an easy solution for various applications requiring a response similar to the human eye through our extensive Ambient Light Sensors. These devices can sense the amount of available ambient light to trigger a response in the specific equipment. These solutions are ideal for applications that require a response influenced by visible light, which can aid in energy conservation in both fixed and portable devices.

Excelitas offers a comprehensive range of Ambient Light Sensor products to enable their integration into various applications. These include the following:

• VTB1012BH - Si PD, TO-46, 1.6mm², IR Filter - a silicon photodiode packed inside a hermetic TO-46 window package. It also comes with a built-in IR rejection filter, which allows it to limit its response into the visible portion of the spectrum while exhibiting a high shunt resistance and low dark current.

• VTB1013BH - Si PD, TO-46, 1.6mm², Low Id - similar to the VTB1012BH that also comes with its own IR rejection filter in order to limit its response to the visible light spectrum.

• VTB6061CIEH - Si PD, TO-8, 37.7mm² - its spectral response closely matches that of the human eye through its built-in filter. This silicon photodiode comes in a hermetic TO-8 flat window package.

• VTP9812FH - Si PD, T-1 ¾, 1.5mm² - designed in a T1 ¾ flat package that blocks infrared light while also providing an excellent response to light in the visible range. It also has very high shunt resistance, low dark current, and low capacitance.

• VTT9812FH - Si Phototransistor, 0.192mm² - similarly comes in an infrared-blocking T1 ¾ flat package and exhibits excellent responses to light in the visible range.

• VTT9814FH - Si Phototransistor, 0.192mm², High Gain - rounding out the series is the VTT9814FH, which also comes in a T1 ¾ flat package that blocks the passage of infrared light. This phototransistor also responds well to the visible spectral range (450 to 700 nm).

Excelitas offers customers excellent, high-performing light-sensing devices that boast robust performance in applications requiring a response from visible light. Through these capabilities, our Ambient Light Sensor solutions can be integrated into the following applications:

• Interior and exterior light switching (dusk/dawn switch)
• Interior and exterior light control (dimming)
• Automotive headlight dimmer
• Display contrast control
• Energy conservation

Excelitas provides a wide range of light sensing solutions that offer excellent performance in various applications. These light sensors have been manufactured while following the strictest standards of production, which enables us to deliver top-notch solutions that are among the top in the industry. While various off-the-shelf products are also available, we also cater to the specialized needs of our customers for various custom applications. Speak to us about the specialized nature of your applications and provide us with your target specifications so we can take care of manufacturing and design.
