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.
Products that realize specifications with a multilayer film structure! We will consider them according to your application and desired specifications.
A "bandpass filter" is a filter that transmits a portion of wavelengths while blocking others. We will consider products that combine multiple filters or utilize multilayer structures to meet your application and desired specifications. 【Features】 ■ Transmits a portion of wavelengths while blocking others ■ Consideration based on your application and desired specifications *For more details, please refer to the PDF document or feel free to contact us.
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.
Design and propose according to the customer's application, including the width of the wavelengths that can pass through and the wavelengths that do not pass through!
This product is a filter that only transmits specific wavelengths and cuts off other light. It is widely used in analyzers, measuring instruments, optical communication devices, sensors, and ultraviolet irradiators. It provides sharp wavelength separation and high transmittance. Fluorescent filters used for fluorescence observation require high optical density, and we can guarantee this from design to manufacturing and spectral measurement. [Application Examples] ■ Medical and Healthcare ■ Analysis and Sensing ■ Semiconductors ■ Communication *For more details, please refer to the related links or feel free to contact us.
This is a card-type unit low-pass filter that is easy to expand. By setting the cutoff frequency for all channels collectively, it achieves a low price.
Optimal multi-channel low-pass filter for anti-aliasing purposes ■ Widely usable for vibration and fluid measurement, among others ■ By implementing a 4-channel filter module in a 16-slot chassis, configurations of up to 64 channels are possible ■ -24dB/oct attenuation, Butterworth filter ■ Cut-off frequencies: 10, 20, 50, 100, 200, 500, 1000 Hz, and bypass ■ Cut-off frequency settings: Front panel (bulk setting for all channels) Remote setting via USB (bulk setting for all channels) ■ The chassis can be stored in an EIA rack (3U) ■ A compact chassis with 2 slots is also available (special specification: manual setting)
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.
