Optical thin film and optical filter contract coating: Design is free for the first time!

We have added a standard stock lineup for the "Near Infrared Bandpass Filter, Wavelength 940nm," which has received numerous inquiries! ■ I want to separate a few pieces for urgent product development and performance testing... ■ I just want to try it out for now... ■ I would like to make a slight change in shape for prototyping... At Adachi New Industry, we sincerely respond to such customer voices! In today's world where simulation technology has advanced, we will provide standard stock items to quickly meet customer requests, so please feel free to contact us! If you are considering a 940nm bandpass filter, please make use of our offerings. We provide filters that maintain their waveform even when the angle changes, meaning they are less likely to lose transmittance even if the angle is misaligned.

A bandpass filter is a filter that enables selective transmission of light for various applications, allowing for the selective exclusion of light at other wavelengths. Based on its proven performance in visible light, it is also optimal for applications requiring delicate light, such as photoelectric sensors (TOF sensors) and LiDAR, by controlling the film formation in the infrared range (940 nm). ◆◆ Are you facing any of these issues? - I want to allow only a specific wavelength in the near-infrared range (940 nm); is that possible? - I would like to use a bandpass filter adapted to the wavelengths of near-infrared LEDs or lasers. - I want to widen the stopband because any light other than the desired wavelength becomes noise. - Can you take into account the range of incident angles? - I've heard it's used in communication devices; does it have any specific features?

Optical technology plays an increasingly important role in our daily lives. Materials with optical functions are abundant around us, such as smartphone screens, car headlights, and building windows. Among them, the optical thin film processing of acrylic resin is a noteworthy technology, and its combination is paving the way for innovative application fields. 【1】Properties of Acrylic Resin Acrylic resin (PMMA) is a polymer of acrylic acid esters or methacrylic acid esters, created by heating methacrylic acid esters. It excels in both transparency and durability, with a light transmittance of 93% and impact resistance that is 10 to 16 times greater than that of glass. Due to its high transparency, it is often referred to as the queen of plastics. 【2】Basics of Optical Thin Films Optical thin films are thin layered materials designed to control the interference and reflection of light. By adjusting the light transmittance and reflectance, various optical functions can be realized. For more details, please visit our expert coating page.

Infrared radiation is electromagnetic waves with longer wavelengths than visible light, and it is invisible to our eyes. However, infrared radiation can penetrate certain resin materials, and may not be absorbed or reflected. This characteristic depends on the chemical composition and structure of the resin. Certain resin materials have high infrared transparency, making them very useful for infrared applications such as infrared remote controls, infrared thermal imaging, and security systems. The infrared transparency of resin materials can be adjusted based on their molecular structure and components, and it is important to select them according to specific applications. (Do you have any of the following challenges?) ■ Is it possible to use resin for substrates to reduce weight? ■ Can we adjust it to allow more efficient transmission in the near-infrared range? ■ I would like to absorb visible light wavelengths; is that possible? ■ I want to suppress light that causes noise and increase the sensitivity of the sensor. Can we discuss this? ■ Is it possible to process it to chip size? Please consider the custom-made optical thin films from Adachi New Industry Co., Ltd. Thank you.
