Analog variable frequency filters require the use of variable passive components. The higher the slope of the filter, the greater the number of needed variable passive components. These elements are ...

In any industrial process that relies on solid-liquid separation, the filter press remains one of the most reliable and widely used pieces of equipment. It delivers consistent dewatering, reduces ...

Without having other variable ND filters for comparison, we can’t make definitive comments on whether the Syrp filter is superior. But we can say that it provides a compact and versatile addition to a ...

Camera manufacturers are consistently working on making cameras capable of capturing more light than ever with fewer noise artifacts. Despite this, there are photographers all over the globe looking ...

The LR2 line reactor series adds seven new frame sizes to match all GS, DURApulse, and WEG drives. The LR2 Series can also be used with a variety of other variable frequency drives (VFD) ...

Across a range of applications, the two most common functions implemented in FPGA-based high-performance signal processing are finite impulse response (FIR) filters and fast Fourier transforms (FFTs).

Responding to the demands of cinematographers & lighting professionals worldwide, Tiffen has launched its new Variable Viewing Filter (VVF), incorporating Tiffen’s award-winning Variable ND filter, ...

Delta Optical Thin Film has lifted the application range of variable filters to new levels by introducing a new powerful type of linear variable filter (LVF) Since Delta Optical Thin Film A/S offered ...

Shooting with a ND filter on your lens is like giving your camera a pair of sunglasses—it cuts light without changing the color balance so you can shoot longer exposures with wider apertures in bright ...

Delta Optical Thin Film has utilised its decades of experience to develop the 4th generation Continuously Variable Short Wave Pass and Continuously Variable Long Wave Pass Filters. A continuously ...
