Fiber Capillary Plate (FCP)

  • High density pore (3um/4um/6um diameter)
  • Length Depth (L/D) up to 200
  • Open Area Ratio (OAR) up to 60-75%
  • Small Non-Linear Coeffcient
  • Very Weak Rayleigh Scattering

Fiber Capillary Plate (FCP) are made of hollow fibers. Within each hollow fiber, there are Cladding,Core, and Air-gaps.

The air holes in the hollow-core fiber can act as a common channel for light and fluid at the same time, and the laser can have a strong direct interaction with the gas or liquid entering the interior of the hollow-core fiber. Moreover, the size of air holes in hollow-core fibers is generally in the range of several micrometers to tens of micrometers. The existence of microchannels not only avoids complex processing technology but also greatly reduces the consumption of samples. Therefore, hollow-core microstructure fibers are used in microfluidics. The detection has a very broad application prospect.

The specification below are refer to the production possibility with a certain type of material combination.
You can customize the Fiber Capillary Plate with specification mentioned below.

wdt_ID Parameter Value Notes
2 Geometric Circular, Square, Rectangles The Geometric here refer to the shape of the plate, not the shape of the Hole
4 Thickness ≥0.3mm Thickness of the plate (which is the same as the depth of the hole), thic
5 Dimension Diagonal 100mm Dimension is the effective area dimension of the plate (Where is covered with Holes)
7 Hore Size regularly start from 4um (1um in experimential) Hole size refer to the hole (pore) diameter, usually smaller hole are more difficult to fabricate
8 Material Borosilicate glass
10 Heat Resistance 500℃ The maximum temperature environment the plates should be used
11 Coating Apply coating inside the pores on the wall available You can apply coating on the wall of the hole
12 Length to Diameter Ratio up to 200x Hole (Length) Depth compared with Hole Diameter, 200x LD ratio is a stable parameter for our Capillary Products.
13 Open Area Ratio above 60% (75% in experimential) The "Holey" area compared with the Effective Area, 60% OAR is a stable parameter for our capillary products.
14 Bevel with or without bevel without bevel the edge area of the plate will not function properly

The capillary stacking drawing process is  most widely used process for microstructure fibers.  Whether the structure is simple or complex, the stacking drawing process can basically be used.
This process can also be applied to fibers of different materials. The stacking drawing process flow is shown in the figure below, the main package is Including the following steps:

1) drawing the capillary glass tube and rod;
2) drawing the capillary glass The glass tubes are stacked into the designed optical fiber structure by the stacking method;
3) Add The outer tube constitutes a microstructure optical fiber preform;
4) At a high temperature of 2000 °C, the optical fiber is drawn by using a special optical fiber drawing tower.
5) Put the optical fiber rod in the support tube, At high temperature, the micro-structured optical fiber is drawn by using a special optical fiber drawing tower
