Added an 800nm short pass filter to the expert coating.

It is an optical filter that selectively transmits light below a specific wavelength and blocks light of longer wavelengths.

The short pass filter can selectively transmit light below a certain wavelength while blocking light of longer wavelengths. This allows for effective handling of light in specific wavelength bands. (Do you have any of the following concerns?) ■ Is it customizable due to its high wavelength dependence? ■ Does performance decrease when light is incident at an angle, and can it be controlled? ■ Is there a possibility of reduced transmittance when blocking specific wavelengths? ■ Can it cause chromatic aberration? ■ Is it difficult to control multiple wavelengths simultaneously?

This is a mirror that reflects near-infrared light, which causes heat. It has a proven track record in projectors and lighting devices where temperature rise is a concern.

1) Are you facing such issues? ■ I want to prevent the temperature from rising due to near-infrared light emitted from the light source. ■ Projectors and lighting devices are getting hot. ■ Is it possible to transmit visible light while reflecting near-infrared (NIR)? ■ Can the wavelength range of the mirror be customized? 2) What is a hot mirror? A hot mirror is used in projectors and lighting devices where temperature rise due to infrared radiation is a concern. By using a hot mirror, it is possible to suppress temperature rise and enable bright light source design. As a coating, it has a special coating that transmits visible light and reflects more than 95% of near-infrared light (NIR). It is used in lighting equipment that employs halogen or xenon light sources, as well as in light source reflection mirrors for medical devices.

It is an optical filter that cuts ultraviolet and infrared light while having a high transmittance in the visible light range.

A UV-IR cut filter is a filter that cuts light in the ultraviolet and infrared regions while having a high transmission rate in the visible light region. In other words, it is an optical filter that simultaneously realizes the properties of both a UV cut filter and an IR cut filter. By placing it in front of CMOS sensors or CCD sensors, it serves multiple roles, such as cutting out noise-inducing light, providing heat protection for various light sources, and preventing degradation of LCD components due to ultraviolet light. It is an excellent optical filter and optical thin film with multiple functions. Are you facing any of these issues? - Is it possible to cut both ultraviolet and near-infrared light? - Can a filter be made that allows visible light to pass while blocking IR and UV wavelengths? - I want to reduce noise light and increase the sensitivity of the sensor. Can I consult with you? - Is it possible to custom adjust the wavelength range that I want to transmit? - Is processing to chip size possible?

It is a dielectric multilayer film filter that transmits visible light and reflects near-infrared light.

It is used as a near-infrared cut filter that adversely affects CCD devices such as video cameras. The optical characteristics, such as the wavelength position with a transmittance of 50%, transmittance, and cut wavelength band, can be set arbitrarily. (Do you have such challenges?) Is it possible to cut only the wavelength of near-infrared light? I want to allow visible light to pass while blocking the wavelengths of IR. I want to suppress light that causes noise and increase the sensitivity of the sensor. Can the wavelength range I want to transmit be custom adjusted? Is it possible to process it to chip size?

[To the owners of parking lots and parking lot construction companies] "I am worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as pedestrian collisions and vehicle-to-vehicle accidents. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask that you arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.

In recent times, there has been a growing interest in infection control measures and facility hygiene management. Our company offers non-contact sensor products that are recommended for commercial facilities, food factories, and nursing and caregiving facilities. 【Sensors for Automatic Doors】 ● Light Touch Sensor HA-T401 … When you wave your hand in front of the automatic door, the sensor detects the movement and opens or closes the door. This is recommended for making doors with touch switches non-contact. ● Hand Wave Sensor PF-R5, PF-U2, DHS-1 … Opens and closes the automatic door by waving your hand in front of the sensor. ● Foot Switch PF-01S/01D/03S/05 … Opens and closes the automatic door by placing your foot in the opening. 【Access Control System】 ● Face Recognition + Unmanned Temperature Measurement DS Series … Allows for face recognition along with mask detection and body temperature measurement simultaneously. ● Automatic Disinfectant Spray Dispenser PHW-03B … Automatically sprays disinfectant when you wave your hand in front of the sensor. 【Nursing and Care Sensors】 ● Infrared Bed Exit Sensor "Just Place It Pole-kun" … This bed exit sensor is installed next to the bed and notifies via nurse call when the subject enters the detection range. ◎ For more details, please download the catalog or contact us.
