安達新産業 Company Overview

When selecting optical thin film filters, many engineers and purchasing personnel first check the "initial performance" such as the spectral transmittance curve and half-width. However, when incorporating them into outdoor equipment or sensor modules, what we really want to know is whether "that performance is maintained after one year or two years." Ultraviolet light, temperature and humidity cycles, rainwater, and dust in the atmosphere—these complex stresses cannot be fully replicated by accelerated testing using constant temperature and humidity chambers or UV exposure test machines. While accelerated tests have the advantage of providing results in a short period, they face the challenge of not being able to provide a definitive answer to the question of "what will happen in actual outdoor environments." Therefore, Adachi New Industry Co., Ltd. conducted an exposure test by installing optical thin film filters outdoors on its rooftop for a full two years to track the temporal changes in optical characteristics. This time, we are specially releasing a portion of the test results and will introduce practical insights that can be gleaned from them.

In the assembly process of electronic devices and automotive parts, the "dripping and flowing" of adhesives has been a long-standing concern in the field. When fixing components on a substrate, the applied adhesive may flow into adjacent circuits, or when applied on inclined or vertical surfaces, it may drip before curing—many engineers have likely experienced such issues. One approach to fundamentally solve these problems is the adoption of non-flowing (non-sag) silicone adhesives. After organizing the meaning of the non-flowing viscosity characteristics and the technical background, we will compare the characteristics of three representative products offered by Momentive—TN8000, TSE3925, and TN5015—based on their TDS, and provide guidelines for selection based on application. 1.

We receive a large number of inquiries from customers considering the development and prototyping of optical thin films. Among these, the most common questions are, "Is it possible to deposit films on resin substrates?" and "Can you accommodate orders starting from one piece?" At first glance, these may seem like simple questions, but they reveal the underlying concerns typical in development environments, such as "I want to keep costs as low as possible for evaluation" and "Since the results are uncertain at this stage, I would like to start with a small-scale trial." However, unlike general processed products, optical thin films can lead to significantly increased development time and costs if the prototyping conditions or substrate selection are incorrect. CASE01: "Is it possible to accommodate resin substrates?" CASE02: "Can you accommodate orders starting from one piece?" CASE03: "Can I consult even without a drawing?" In the prototyping of optical thin films, "an optimal development plan" is more important than "minimum quantity." Optical thin films are a highly advanced technical field where numerous factors, such as substrate materials, wavelengths, angles, and environmental conditions, interact with each other. Therefore, organizing the application and required performance from the early stages of development and consulting with a reputable manufacturer is the shortcut to success.
