Midopt Long Pass Filter
A long pass filter transmits light with wavelengths longer than visible light and near-infrared light, while blocking shorter wavelengths. Primarily used in monochrome image processing applications, the long pass filter can enhance contrast, resolution, and color while maximizing the brightness of the surroundings of the inspected or monitored object.
Various optical filters from Midopt.
Bandpass, multi-bandpass, long pass, short pass, near-infrared cut filter, polarizing filter sheet, ND filter, color balance (color correction) filter, protective acrylic filter. Filters from Midopt improve contrast, reproducibility, and stability in industrial vision systems, providing the simplest and most cost-effective solution.

3dB bandwidth: High-performance high-pass filter from 150kHz to 3GHz
A 150 kHz high-pass filter protects the RF input of a spectrum analyzer or EMI receiver from residual 50 Hz voltage in high-amplitude subharmonics and conductive emission measurement setups.
It is a filter designed to transmit light in two specific wavelength bands while blocking (preventing) other wavelength bands. It is ideal for surveillance cameras and similar applications.
1) Are you facing such issues? ■ Is it possible to transmit visible light and part of the infrared wavelength (850nm)? ■ I want to ensure that the blocking range that causes noise is definitely cut off. ■ Since there is a range of incident angles, can this be taken into account? ■ The shape is special; can it be shipped as a component? 2) Dual-band pass filter (multi-band pass filter) This is a filter designed to transmit light in two specific wavelength bands while blocking (preventing) other wavelength bands. In addition to standard IR cut, it has the function of selectively transmitting only specific near-infrared wavelengths (such as 850nm, 905nm, 940nm, 1064nm). For example, it is ideal for applications that require monitoring both during the day and at night by transmitting specific visible light and specific near-infrared light. With 40 years of experience, we have achieved sharp wavelength separation and high transmission rates. Our unique control technology during film formation allows for high durability and reduced shift.
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?

Supports 150M/260M/400M band for business use wireless bandwidth.
When measuring harmonics generated from devices such as radios with a spectrum analyzer (specan), the analyzer itself can generate harmonics by receiving the fundamental wave, which can lead to significant measurement errors, especially when measuring low-level harmonics. This high-pass filter for harmonic measurement removes the fundamental wave and allows harmonics to pass through, thereby reducing the input of the fundamental wave to the spectrum analyzer and also decreasing the harmonics generated by the analyzer. This product can be used as a measurement auxiliary device to improve accuracy. 【Features】 - Compatible with 150M/260M/400M band commercial radio frequencies - Attenuates the fundamental wave frequency band by over 40dB - High input capability: 30W For more details, please contact us or download the catalog.

Entering the waveguide business for 5th generation communication (5G)! We will support the communication needs of "millimeter waves" (radio waves with wavelengths from 1 millimeter to 10 millimeters)!
Metal is used for waveguides that ensure strong directivity in millimeter wave transmission, making it difficult to bend and wire at free angles. However, while "flexible waveguides" have slightly higher transmission loss values, they exhibit minimal changes even when bent sharply. For more details, please refer to the "Flexible Waveguide Manual" or the "Nikkankogyo Shimbun Waveguide Description."
