[[ Brief summary on current situations ]]
1) TAMA beam height from the floor is set to be 1200mm.
2) Current height of TAMA optical tables are 900mm.
Here the height is that of tabletop surface.
We are using Newport RS4000 Series optical tables.
Table thickness is 8 inches.
Leg height (nominal) is 28 inches. This is the longest leg in catalogue products.

3) Now a beam height from the table is under discussion.
Possible height is 2 inch to 3 inch.

[[ KAGRA ]]
I found the following Wiki page on KAGRA output optical tables.
http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/IOO/OutputTables
Because of ground surface curvature,
the table height depends on each optical port.
The range is 0.940 to 1.000 meter in height.
Guideline for beam height and periscope [in Japanease]
http://gwdoc.icrr.u-tokyo.ac.jp/DocDB/0026/D1402607/001/TableHeight.pdf
* Beam height on the table is fixed to be 3 inches.
* The height gap between the table and output/input beam should be
greater than 7.6 inches. (NOT LESS THAN)
* By using periscope the height gap are solved.

[[ Questions to Aso-san ]]
[Q1] What are the limiting factors for table height of one meter?
KAGRA beam height and requirements for periscope are determined the table height.
(I guess there is no technical limiting factors for the table height)
[Q2] Please tell me the product company and its number for REFL port's table.
Product number: LBHD-2412TS (2400x1200x940H)

[[ Possible solution ]]
I ask an japanease agency of Newport product about the legs.
They said that Newport can provide us custom-made legs.
To check the details of the table, they will come to TAMA site.
After that, I can get a quotation for it.
That's all
