We will be exhibiting at interOpto2025 / Light and Laser Science and Technology Fair (Ultraviolet Fair).

"IHU250H" is a moldable ultraviolet-transmitting glass that can be processed at lower temperature ranges compared to quartz and has a thermal expansion rate close to that of metals.

【Product Introduction: IHU250H】 The "IHU250H" is a glass that functions as an optical glass filter that transmits ultraviolet light while also being usable as a molding material. Its lower processing temperature compared to quartz and thermal expansion rate closer to that of metals make it suitable for metallization. For detailed optical properties, please refer to the downloadable materials. 【Features】 ■ Processing temperature range is lower than that of quartz (1600-1700℃) (IHU250H: 563℃) ■ Thermal expansion rate is closer to that of metals than quartz, making it suitable for metallization ■ Available for sale as molding materials such as block materials, rod materials, and ball lenses

Consistent production from prototype to mass production through innovative technology.

Product Introduction: Glass Molded Lenses Glass molded lenses, created through die-casting molding, achieve complex shapes that are difficult to produce through polishing and lens structures that previously required assembly, all in a single molding process. Most products are fully customized according to customer requests, with flexible support from prototyping to mass production. In addition to the lens molding technology developed over many years, we utilize unique measurement and inspection techniques to provide high-precision products. We cater to a variety of shapes and specifications, including not only lens arrays but also aspherical lenses, Fresnel lenses, rod lenses, and irregularly shaped lenses. Features ■ Integrated glass lenses through molding ■ Achieves complex shapes and integrated structures, enabling shapes that are difficult to polish ■ Supports prototyping to mass production with full customization ■ Proven track record with various shapes including aspherical lenses, Fresnel lenses, rod lenses, and irregularly shaped lenses ■ Guarantees high quality with unique measurement and inspection technologies

[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.
